Perspectives and Frontiers by RSC award winners

16 Feb 2016

We are delighted to present a selection of recently-published Dalton Transactions Perspective and Frontier articles by recent winners of Royal Society of Chemistry awards.

Dr Adrian Chaplin: 2015 Harrison-Meldola Memorial Prize winner

NHC-based pincer ligands: carbenes with a bite
Rhiann E. Andrew, Lucero González-Sebastián and Adrian B. Chaplin
Dalton Trans., 2016, 45, 1299
DOI:10.1039/C5DT04429D

In this frontier article we overview the emergence and scope of NHC-based CCC and CNC pincer systems, i.e. complexes containing mer-tridentate ligands bearing two NHC donor groups, comment on their effectiveness in applications, and highlight areas for future development and exploitation.

Professor Paul Dyson: 2015 Bioinorganic Chemistry Award winner

Metal-based drugs that break the rules
Claire S. Allardyce and Paul J. Dyson*
Dalton Trans., 2016, Advance Article
DOI: 10.1039/C5DT03919C

Cisplatin and other platinum compounds have had a huge impact in the treatment of cancers and are applied in the majority of anticancer chemotherapeutic regimens. The success of these compounds has biased the approaches used to discover new metal-based anticancer drugs. In this perspective we highlight compounds that are apparently incompatible with the more classical (platinum-derived) concepts employed in the development of metal-based anticancer drugs, with respect to both compound design and the approaches used to validate their utility. Possible design approaches for the future are also suggested.

Dr Kogularamanan Suntharalingam: Dalton Young Researchers Award 2014 Winner

Advances in cobalt complexes as anticancer agents
Catherine R. Munteanu and Kogularamanan Suntharalingam*
Dalton Trans., 2015, 44, 13796-13808
DOI: 10.1039/C5DT02101D

The evolution of resistance to traditional platinum-based anticancer drugs has compelled researchers to investigate the cytostatic properties of alternative transition metal-based compounds. The anticancer potential of cobalt complexes has been extensively studied over the last three decades, and much time has been devoted to understanding their mechanisms of action. This perspective catalogues the development of antiproliferative cobalt complexes, and provides an in depth analysis of their mode of action.

Professor Philip Mountford completes his final term as Chairman for Dalton Transactions

04 Dec 2015

Professor Philip Mountford (University of Oxford) will complete his final term as Chairman of Dalton Transactions’ Editorial Board at the end of December this year.

Philip, Chairman of the Editorial Board since January 2012, has been a fantastic ambassador for the Journal, representing Dalton Transactions at many conferences around the world. He has overseen 4 Editorial Board meetings (including at the 2013 Royal Society of Chemistry Editors’ Symposium in Brussels), guest edited two themed issues (Advances in metal-catalysed polymerisation and related transformations, and Earth Abundant Element Compounds in Homogeneous Catalysis) and chaired the Editorial and Advisory Boards of Dalton Transactions during a period of significant expansion of the Journal’s published volume.

He leaves Dalton Transactions in a very strong position, with the Journal reporting its highest ever impact factor for 2014 (4.19) and publishing over 2000 articles a year – the only weekly international journal for inorganic, organometallic and bioinorganic chemistry.

Philip’s work on the Journal was recognised at a presentation, held during one of his last engagements for Dalton Transactions – chairing the final session of the 2015 RSC Coordination and Organometallic Chemistry Discussion Group Meeting (Oxford, 3-4 September 2015), during which Professor Jason Love (University of Edinburgh) was the Dalton Transactions-sponsored Plenary lecturer.

This was an especially relevant meeting, as Philip is Head of Inorganic Chemistry and Professor of Organometallic Chemistry and Catalysis at Oxford.

Philip was presented with a framed portrait of John Dalton, the Journal’s namesake, as both a token of our appreciation and to commemorate the 250^th anniversary of John Dalton’s birth. Philip was also presented with a Dalton Transactions mug featuring the cover image of the 2013 themed issue that he guest edited.

Among his numerous other important contributions and achievements during the past four years, Philip helped to celebrate the work of Dorothy Hodgkin, represented Dalton Transactions at its 4th International Symposium, and received the Schlenk Lectureship award in 2015.

Professor John Arnold (University of Berkeley, California) will succeed Philip as Chairman of the Editorial Board, from 1^st January 2016.

“I am delighted that John Arnold will be taking over as Chair of the Editorial Board,” said Philip. “I know that under his leadership the board and editors will take the journal on from strength to strength. I have been very privileged to work with an outstanding group of professionals in the Dalton Transactions Editorial team and an equally talented and dedicated board.”

Thank you, Philip! We’ve been very privileged to work with you.

Adjusting the Pincer Pinch

02 Dec 2015

Professor Darrin Richeson’s group has carved out an interesting organometallic niche. Their papers feature low-valent metal complexes of pincer ligands combined with detailed computational analysis of the electronic structures. In their recent Dalton Transactions article they report unique coinage metal complexes of the “PN³P” ligand below.

The judicious selection of this particular pincer framework resulted in complexes with geometric properties distinct from those of the same metals with other “PNP”-type ligands. Choosing the ligand with a NR instead of a NH spacer between the pyridine and phosphine moieties enhances the donor strength of the phosphines while rendering the N atoms inert towards deprotonation.

Subtle effects of this adjustment manifest themselves in dramatic changes in the solid-state coordination and geometric properties of their Cu and Ag complexes. Their reported CuBr complex is coordinated by one PN³P ligand and has a distorted trigonal pyramidal geometry. They contrast these to Cu(I) complexes of an analogous PN³P ligand with NH spacers, which coordinate two ligands and in one case displace the halide atom. Using CH₂ spacers, a previously reported Cu(I) structure exhibits T-shaped geometry and a non-coordinating triflate anion. The Cu(I) reported here shows a geometry much closer to trigonal pyramidal, with a coordinating triflate anion.

The second part of the paper discusses details of the electronic structure gleaned from DFT calculations. Particularly illuminating is a paragraph on page 19157, summarizing the particulars of the bonding as “a balance of bonding and antibonding interactions…diffuse polarized-π orbitals…(and) back donation.” Perhaps this seems summary seems unsurprising, but there are subtleties in the analysis.

Professor Richeson was my M.Sc. supervisor (I finished in his group six years ago). I write this in gratitude for his mentorship, and in appreciation of his group’s continuing work.

Report from the Northern Postdoctoral Researchers Meeting

25 Nov 2015

The Northern Postdoctoral researchers meeting took place on May 28^that the School of Chemistry and Zochonis Building, The University of Manchester. This was the fourth of a series of events organised by the Chemistry Postdoctoral Society for the academic year 2014/15, included in the proposal funded by the Dalton Division Committee through the Small Grants for Scientific Activities scheme.

The purpose of the meeting was to gather young scientists from the Northern and North-West region, giving the chance to showcase their research and offering also a great networking opportunity. The event was free to attend and saw the participation of around 70 attendants between Postdocs and PhDs coming from the University of Manchester, University of Liverpool, University of Huddersfield, University of Sheffield, University of Hull, University of York, and University of Leeds.

Postdoctoral researchers selected from Northern institutions (Manchester, Huddersfield, Hull, Leeds and Liverpool) offered research talks which spread across a wide range of topics in chemistry. The quality of the talks and of the research presented was outstanding, leading also to a great interaction between the audience and the speakers.

After the coffee break, the meeting was moved to the foyer of the School of Chemistry were the poster session took place, featuring over 30 contribution from Postdocs and PhD from various Northern institutions. At the end of the poster session, two prizes were awarded, sponsored by Dalton Transactions. The winner of the prize for the best postgraduate poster went to Luke Wilkinson (University of Sheffield), whilst the prize for the best poster from a postdoctoral researcher was awarded to Kevin Vincent (University of Huddersfield).

In general, we received very enthusiastic feedback about the meeting. In particular, visiting postdoctoral researchers had high praises for the work of the Postdoctoral Society and offered to organise another event analogous to this in one year’s time.

The meeting was kindly supported by the RSC Dalton Division and the School of Chemistry (UoM). Furthermore the Postdoctoral Society obtained additional support from Fluorochem, Sigma-Aldrich and TCI. Dalton Transactions was acknowledged during the opening and closing remarks of the conference; additionally the Dalton Transactions logo was included in the conference material.

Professor Kenneth Wade, F.R.S. 13th October 1932–16th March 2014

10 Nov 2015

This themed collection of articles in Dalton Transactions is dedicated to Ken Wade, who very unexpectedly passed away on 16^th March 2014. While this sad loss is the reason for this commemoration, it is an honour for me to write this preface.

I had the pleasure and privilege of getting to know Ken personally during my student days at Durham, a relationship that continued when, much more recently, I became a colleague in the same Department.

I first met Ken when, as a second year undergraduate, he introduced us to aspects of structure and bonding. Only after looking up the subject in the textbooks, did I realise that the relationships he was describing were in fact ‘Wade’s rules’.

It is a vivid reflection of Ken’s humble and self-effacing character that he himself only ever referred to these rules as polyhedral skeletal electron pair theory (PSEPT) or even occasionally during his lectures or in discussions as “Blogg’s Rules”!

Ken’s pioneering work exploring and explaining the structures of deceivingly unrelated clusters and ring systems, which developed primarily as a result of his insightfulness, logical thinking and intuition, now means that his name is familiar to every inorganic chemist, from undergraduate student to senior research professor.

This work lead to the formalised relationship between structure and electron counting in polyhedral cluster systems: relationships that are known universally as Wade’s Rules (J. Chem. Soc. D, 1971, 792).

This set of deceptively simple rules has been developed and expanded into what are known today as the Wade-Mingos Rules, which continue to be taught to chemistry students worldwide as a fundamental tool of Inorganic Chemistry.

Ken’s research career started in 1954 when he began his Ph.D. at the University of Nottingham with Norman Greenwood, probing the addition compounds of gallium and boron trichlorides. This was followed by two postdoctoral positions: first at Cambridge with Harry Emeléus, working on “assorted reactions of diborane”, and second, at Cornell University with Albert Laubengayer, where he investigated various aspects of organonitrogen-aluminium chemistry.

In 1960, Ken returned to the UK to take up his first independent academic position as a lecturer at Derby College of Technology, before moving north to take up a lectureship at the University of Durham a year later, where his interests in synthetic main group chemistry continued to expand.

Although universally known for his electron counting rules, Ken’s innovative and creative character also led him to be major contributor to the areas of azomethine, lithium amide, organophosphorus, transition metal and organolithium chemistry, to name but a few. Ken officially retired in 1997 and, for the sixteen years leading up to his untimely passing, he remained in the Department holding an Emeritus chair of Inorganic Chemistry.

Throughout his sixty-year research career Ken maintained a tireless enthusiasm and curiosity for chemistry, teaching, writing books and original papers, reviewing articles, attending chemistry meetings, and giving invited lectures around the world. Ken’s numerous contributions to the broad field of chemistry were recognised by his election to Fellow of the Royal Society in 1989, and by his election to President of the Dalton Division of The Royal Society of Chemistry in 1996.

On top of all these achievements, Ken’s enormous abilities as a teacher and leader must not be forgotten. His lectures were always inspiring, and were characterised by being both simple and clear, while delivering a broad spectrum of inorganic chemistry topics.

Every lecture was punctuated by anecdotes and amusing stories – who can forget the colour-blind English spy in Russia – and always demonstrated Ken’s ability for clear, logical thinking, something he continually encouraged and inspired in others, be it through undergraduate tutorials, questions after seminars, or chats in the corridor or around the whiteboard.

This themed collection of papers of 60 papers in Dalton Transactions covers a wide and diverse spectrum of topics spanning inorganic chemistry, something that very clearly demonstrates Ken’s significant and wide-ranging contributions to inorganic chemistry in its broadest context.

The rapidity with which all of the invited authors agreed to contribute their work to this special collection of articles unmistakeably reflects the great esteem and friendship with which Ken was held, and provides a fitting tribute to the man himself, his huge role as a teacher and mentor, and his important and extensive contributions to chemistry… Without a doubt, Ken is very sorely missed.
