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.

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……….

We are proud to announce that the International Symposia on Advancing the Chemical Sciences (ISACS) series will return in 2012 to include Challenges in Inorganic and Materials Chemistry (ISACS8) on 19 – 22 July in Toronto, Canada.
A range of topics will be covered including catalysis, organometallic chemistry, porous materials, main group chemistry, magnetism and materials for energy.
Full details surrounding the confirmed speakers and abstract submission process can be found on the dedicated webpage for this significant global conference.
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.
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.

Can we mimic the Photosystem II machinery for light-driven oxidation of water to molecular oxygen?
In this Dalton Transactions Perspective, Philipp Kurz and colleagues discuss manganese-containing compounds that have been studied as potential analogues of the oxygen-evolving-complex in Photosystem II. They highlight how the desire to produce solar fuels is inspiring research into artificial photosynthesis.

Luminescent iridium complex surfactants form spherical aggregates in water, changing from red to green on aggregation, scientists from Germany and Italy have discovered.
The team, led by Luisa De Cola, say that the aggregates have different properties to the single components, and that the change between them could enable this system to be used as a probe for bio-imaging and bio-labelling.
