This week’s issue of Dalton Transactions contains an excellent review from Ann Valentine, of Yale University.
Her perspective article focuses on the how the ascidians, which are marine invertebrates commonly known as sea squirts, control how metals like vanadium, titanium and iron react in water.
The sea squirts are amazing creatures that have an unparalleled ability to keep high concentrations of vanadium in their cells, and are an excellent way of studying biological control over inorganic coordination chemistry.

A new US-based Associate Editor for Dalton Transactions … Professor Dan Mindiola
I am delighted to announce that Professor Dan Mindiola based at Indiana University at Bloomington in the USA has recently joined the Dalton Transactions team as Associate Editor.
Dan will join the journal’s three existing Associate Editors, Professor John Arnold based at University of California, Berkeley, USA, Professor Guo-Xin Jin at Fudan University, China and Professor Russell Morris from St. Andrew’s University in the UK.
From June 2011 you will be able to submit your manuscripts to Dan for consideration in the journal using our online submission system.
Dan’s research work entails the design and assembly of reactive metal complexes of early metals and their role in unusual transformations such as C-H activation and C-N bond cleavage reactions. He is also interested in novel catalytic processes mediated by reactive complexes containing metal-ligand multiple bonds.

In this Dalton Transactions Hot Article, En-Bo Wang and colleagues synthesised two nanosized, hexameric POM-based solid assemblies, decorated with six 3d–4f heterometallic clusters: (H2en)6Na15K9[Dy6Fe6(H2O)12(SiW10O38)6]·34H2O and K13Na17[H2en]3[Tb6Fe6-(H2O)12(SiW10O38)6]·40H2O.
The assemblies were synthesised by a hydrothermal method and characterised by IR, elemental analyses, magnetic studies and single crystal X-ray analysis. The use of organic ligands, pH and reaction temperature all play an important role in the synthesis. The magnetic studies suggest the presence of antiferromagnetic interactions in both compounds.

In a collaboration between researchers at the University of Oxford, Nankai University and Tsinghua University, Luet-Lok Wong and colleagues determined the substrate-free crystal structure of a variant of CYP102A1 (P450BM3) with generic activity-enhancing properties (KT2).
The electronic properties and the catalytic behaviour of KT2 were investigated and the authors proposed that the rate accelerating properties arise from the substrate-free form being in a catalytically ready conformation, such that substrate-induced changes to the structure play a less significant role in promoting the first electron transfer than in the Wild Type.
This Hot Article will be included in a themed issue of the journal to celebrate 40 years of Dalton Transactions.

Fe–H stretching frequencies occur in the same spectral window as the C–O stretching frequencies, with lesser intensity, and both stretches are strongly coupled in some structures. Symmetrical bridging of CO between two Fe atoms of FeMo-co is destabilised by the presence of other ligands on Fe, and the reason for this is evident. Two results for bound formyl, HCO, are reported. These calculations of reference structures allow some interpretation of existing experimental spectra, but, perhaps more significantly, they suggest further kinetic infrared experiments to elucidate the chemical mechanism of catalysis by nitrogenase under normal turnover conditions.

The well-ordered arrangement of the nanopillars can produce vertical mesoporosity in the films.This porosity can be regarded as “inverse mesospace” of a 2D hexagonal structure with “mesochannels” running perpendicular to the substrate. This vertical mesoporosity in films is very exciting as it can enhance pore accessibility broadening the potential applications of these already much studied mesoporous metal oxides.
