Dalton Transactions: at the heart of the inorganic community

Posted on behalf of Jamie Humphrey, Editor

Our number one priority at Dalton Transactions is to ensure that the journal continues to support our community by providing excellent services for authors and by publishing only the best inorganic chemistry research. We strive to develop and innovate to make sure that the journal continues to serve the international inorganic community. This is very much at the heart of everything we do.

The truly international nature of the journal is represented not only in our authorship (we published articles from 70 countries in 2012), but also through the Editorial Board membership, including our team of Associate Editors – about half of the papers submitted to the journal are handled by this team, with the rest handled by the team of Editors based in Cambridge. Our Associate Editors span the globe, with editorial offices in the USA, UK, Germany, China and Japan. The Royal Society of Chemistry has also been developing its international staff presence in recent years and we now have editorial staff based in Japan, China and the USA, in addition to Royal Society of Chemistry offices in India, Africa and, more recently, Brazil.

In today’s information age, where we can sometimes feel overwhelmed with the amount of information that is available, access to reliable trustworthy knowledge has never been more important. At Dalton Transactions, our fair and impartial peer-review means the content we publish is always of the highest possible quality. Ensuring your research gets the right audience is also key. We have therefore introduced initiatives to lead to greater discoverability for articles published in the journal, and to develop additional measures of an article’s impact.

Dalton Transactions is part of a pilot programme between the Royal Society of Chemistry and Kudos, which aims to provide tools and services to help researchers maximise the usage and impact of their articles. The need for Kudos arises from developments in global academic and research policies that see evolving measures of ‘impact’ used to assess excellence. Kudos aims to provide a service to help researchers and their institutions measure, monitor and maximize the usage of and citations to their articles. The Royal Society of Chemistry also recently introduced a new system for monitoring article-level metrics in Dalton Transactions. The service collates online “mentions” of scholarly articles from social media, newspapers, blogs and other sources into a report that appears online with the article to showcase its uptake, visibility and societal impact. Article-level metrics represents a shift from measuring the impact of a journal to the impact of an article.

Supporting the community is at the heart of Dalton Transactions and is also at the core of the Royal Society of Chemistry, the world’s leading chemistry community. One way in which we supported chemists across the globe is through the funding of the International Year of Chemistry legacy grants. In 2012, over 60 of our member groups received grants each of £1000 to arrange events and activities to promote the chemical sciences. These had an international nature, and ranged from workshops for migrant children in Beijing and a science fair on water chemistry in southern India to supporting chemistry education in tsunami-affected areas in Sri Lanka. Learn more about these grants via www.rsc.org/scienceandtechnology/funding/iyclegacygrants.asp

Dalton Transactions continues to publish research from all areas of inorganic, organometallic and bioinorganic chemistry. Our Themed Issues bring together the best articles in topical research areas or highlight emerging subjects. Table 1 gives full details of the Themed Issues published in 2013.

To discover which conferences the Editorial Team will be attending in 2014, follow us on twitter (@DaltonTrans and @humphreyj).

We were pleased to support a number of international conferences in 2013 through sponsorship – you may even have attended one of our sponsored lectures. We give support to younger members of the community via poster prizes, and in 2013 we awarded 22 poster prizes, celebrating the achievements of members of our community in the early years of their academic careers. If you are organising a conference in 2014 and you would like us to sponsor a poster prize, please let us know.

With a thriving worldwide network, and a not-for-profit ethos, the Royal Society of Chemistry is the best place to publish work that advances excellence in the chemical sciences. Publish with Dalton Transactions and you’ll be supporting the wider scientific community and future generations of chemists and chemical scientists.

Have a fantastic 2014!

Dalton Transactions now features Altmetrics

We are pleased to announce the inclusion of Altmetrics on Dalton Transactions.

With a constantly changing publishing landscape and changes to the way people use scientific literature, altmetrics is a measure that can monitor the level of conversation and interest in a particular piece of research at the article level. Thus altmetrics provides an additional modern metric for our authors to measure the impact of their work, rather than rely solely on citations and impact factor.

To view the altmetrics on Dalton Transactions articles, use the Metrics tab as pictured below on the article landing page.

Altmetrics on Dalton Transactions

A press release from Altmetrics is available on our website.

What do you think? We are interested to hear your feedback on this new development and how you are utilising these new types of metrics. Please leave your comments below.

Why Some Silylenes Split Hydrogen and Others Don’t

Posted on behalf of Ian Mallov, web writer for Dalton Transactions

We often invoke the analogy of using building blocks when we talk about constructing large, complex molecules.  Adding small building blocks often allows for finer control in design, and diatomic hydrogen is the most used small building block.

To add hydrogen to other molecules, hydrogen molecules themselves are split into a proton and hydride; these are then transferred to the target molecule.  Recently, main group compounds involving frustrated Lewis pairs have been used in both steps instead of transition metal catalysts.  There are also a few main group molecules where hydrogen is split at a single atomic site.  Silylenes – the silicon analogue of carbenes, and the subject of this paper, with two bonds, a pair of electrons, and an empty p-orbital, are one type of these select few. This paper mentions the argument that non-transition metal catalysts may be “greener,” but a thorough life-cycle analysis of extraction, reaction and disposal would be necessary to indicate this. 

Authors, Kuriakose and Vanka use Density Functional Theory to explore the question of why some silylenes split hydrogen and some don’t.  Specifically, they want to test the hypothesis that whether or not hydrogen is split at the silicon centre depends on if an adjacent atom “interferes,” leading to undesired products.  They create a profile of the energies of reaction (with hydrogen gas) of three distinct types of silylene: a boryl amido silylene (I), a silyl amido silylene (II) and a dithiolate silylene (III).  I and II have activated hydrogen, while III hasn’t been observed to do so. 

 

The free energy profiles for the reaction of silylene, III, with hydrogen  

After optimizing geometry they model the HOMO and LUMO of the silylenes, since donation of electrons from the HOMO and acceptance of electrons into the LUMO are necessary for hydrogen activation.  In the case of I and II, the LUMO is localized on the silicon atom, while in III, it is not. Correspondingly, the reaction pathway of splitting hydrogen is energetically favoured for I and II, and disfavoured for III.  They also examine effects of other features, such as the angle of the two substituents.

Ian Mallov is currently a Ph.D. student in Professor Doug Stephan’s group at the University of Toronto. His research is focused on synthesizing new Lewis-acidic compounds active in Frustrated Lewis Pair chemistry. He grew up in Truro, Nova Scotia and graduated from Dalhousie University and the University of Ottawa, and worked in chemical analysis in industry for three years before returning to grad school.

Unexpected interactions for piano-stool carbene complexes

A team of researchers from France, Spain and Russia have put forward a case to explain a counter-intuitive conformation of manganese alkylalkoxycarbene complexes.

Using molecular orbitals, it is predicted that such complexes adopt a vertical coordination mode. This is largely the case – although one exception reported by Landman et al. earlier this year (see here) prompted the team to investigate what really is going on…

Coordination modes of carbene ligands in piano-stool complexes

Using a combination of DFT calculations and XRD analysis, Lugan et al. confirm that non-covalent interligand interactions between the alkyl substituents on the carbene and the carbon monoxide ligand (C-HC≡O) are responsible for these complexes adopting the unexpected horizontal coordination mode. Although such an interaction is weak, it goes to show that its enough to influence geometry.
