First came Pacman, then Ms. Pacman and now Diamido Pacman!?

02 Dec 2011

Multi-dentate amido ligands are a real area of interest in coordination chemistry, the transition metal complexes possess novel reactivities, interesting structures and a range of properties including magnetism. Diamido-donor ligands for a large number of diamagnetic metal centres have been well studied, but the paramagnetic complexes have been relatively unexplored. Daniel B. Leznoff and Cassandra E. Hayes have compiled a review of these interesting structures in their Dalton Transactions Perspective ‘Paramagnetic metal complexes of diamido donor ligands‘, highlighting the broad scope of research yet to be undertaken. Who knows where the next fruit will appear in this unexplored maze?

‘Dalton Transactions after 40 volumes’ – Peter Scott

30 Nov 2011

It has been a year of celebration for Dalton Transactions. As many of you will have heard it is 40 years since the journal began publishing works of great inorganic chemistry and as part of these celebrations Peter Scott has written a historical account of his personal experience with the journal. Peter still remembers his first Dalton Transactions paper as an undergraduate and has since seen the abundant changes that have led to the modern day interactive journal that needless to say is still publishing great inorganic chemistry. Peter’s historic perspective is an insightful read.

Gaseous silanetriols: partners or loners?

24 Nov 2011

Silanetriols are compounds of the general formula Si(OH)₃R which readily form polysiloxanes by condensation, by substituting R for condensation resistant ligands a range of crystal structures have been identified for different solid state silanetriol compounds. Norbert W. Mitzel and colleagues have been investigating the intermolecular forces of gaseous silanetriols, the first investigation of its kind, with the aim of discovering if tert-butylsilanetriol [tBuSi(OH)₃] dimerises via H-bonds or remains monomeric when in the gas state.

Intrigued? To find out more about the teams findings, including the taste of their silanetriol, read the full HOT article which is free to access until the 20^th of December

HOT Article: Catalysing the Suzuki-Miyaura Coupling

23 Nov 2011

The Suzuki–Miyaura cross-coupling of aryl halides with organoboronic acids is an important tool for synthetic organic chemistry. A range of palladium complexes with different ligands can been used to catalyse this interesting reaction and Ajai Kumar Singh and co-workers have synthesised four new ligands (selenated Schiff bases) to investigate the influence alkyl chain lengths have on the [Pd(L–H)Cl] complexes and their catalytic efficiency. Their remarkable results indicate there is a correlation between ligand alkyl chain length and catalytic efficiency, however, as their Dalton Transactions HOT Article details, the Pd(II) complexes are pre-catalysts which generate in situ real catalytic species of approx. 3 nm Pd(0) nanoparticles, protected by organoselenium species……….

To find out more about this fascinating discovery read the full article which is free to access until the 20th Decemeber.

Poster prize winner Dr Subash Sahoo at the ACC3

16 Nov 2011

We are very pleased to report that at the 3rd Asian Conference on Coordination Chemistry (ACC-3), Dr Subash Sahoo, from the group of Prof. Rahul Banerjee of the National Chemical Laboratory in Pune, was awarded the Dalton Transactions poster prize! His winning poster focussed on chiral coordination networks and proton conductivity along helical chains of hydrogen-bonded water molecules. More details of the conference can be found here.

Dr Sahoo was awarded a Dalton Transactions certificate and a copy of the book Coordination polymers: design, analysis and application, which unfortunately he could not receive in person, but was accepted on his behalf by Prof. P. K. Bharadwaj.

The RSC Advances poster prize was awarded to Sandeep Kumar Dey for his poster on anion binding and host-guest chemistry with tripodal ligands, details for which can be found on the RSC Advances Blog.

HOT Article: Different solvents mean different packing

16 Nov 2011

Rational design of MOFs is a complex task with a range of variables including ligands, metals, reaction conditions and solvents, this HOT Communication in Dalton Trans. details the synthesis of a novel metal organic framework (MOF) using an aromatic linker and CdBr₂. Leonard Barbour and Marike du Plessis synthesised the framework with different solvents and discovered different packing modes for the different solvent systems…… to find out more about their discoveries read the full Communication in Dalton Transactions.
