Book Description
There has been enormous progress in our understanding of molybdenum and tungsten enzymes and relevant inorganic complexes of molybdenum and tungsten over the past twenty years. This set of three books provides a timely and comprehensive overview of the field and documents the latest research. Building on the first and second volumes that focussed on biochemistry and bioinorganic chemistry aspects, the third volume focusses on spectroscopic and computational methods that have been applied to both enzymes and model compounds. A particular emphasis is placed on how these important studies have been used to reveal critical components of enzyme mechanisms.This text will be a valuable reference to workers both inside and outside the field, including graduate students and young investigators interested in developing new research programs in this area.

Book Description
Abstract: W2(mhp)4 was examined as a starting material for the synthesis of the evasive ditungsten tetracarboxylates with the following carboxylic acids: 2-thienylcarboxylic acid, benzoic acid, 9-anthracenylcarboxylic acid (Anth-9-CO2H), and 2,4,6-triisopropylbenzoic acid (TiPB). It was determined that the reaction of W2(mhp)4 and Anth-9-CO2H provides a convenient preparatory method for a W2(O2CR)4 complex. The synthesis of the series, Mo2(mhp)4-x(TiPB)x (where x = 1-4), was attempted to illustrate the ability to selectively modify the electronic structure of paddlewheel complexes. The complexes corresponding to x = 0, 1, 2, and 4 have been synthesized and UV-vis results implicate the ability to control electronic features via stepwise mhp-carboxylate ligand substitution. Dimolybdenum paddlewheel complexes were linked with both 2,5-thienyldicarboxylate and 3,4-thienyldicarboxylate as an attempt to probe the effect that linker geometry has on the electronic properties of the coupled "dimers of dimers". The complexes were characterized via electrochemical methods and UV-vis spectroscopy. The complex, [Mo2(mhp)2(CH3CN)4][BF4]2, has been synthesized and its structure has been determined by single crystal X-ray crystallography. The reaction of this dication with a dicarboxylate salt was determined to yield a mixture of molecular triangles and squares by mass spectrometry.
