Monodentate heteroligand complexation

Equilibrium Constants for Selected Monodentate Heteroligand Complexes of Bisperoxovanadate9... 

This book does not follow a chronological sequence but rather builds up in a hierarchy of complexity. Some basic principles of 51V NMR spectroscopy are discussed this is followed by a description of the self-condensation reactions of vanadate itself. The reactions with simple monodentate ligands are then described, and this proceeds to more complicated systems such as diols, -hydroxy acids, amino acids, peptides, and so on. Aspects of this sequence are later revisited but with interest now directed toward the influence of ligand electronic properties on coordination and reactivity. The influences of ligands, particularly those of hydrogen peroxide and hydroxyl amine, on heteroligand reactivity are compared and contrasted. There is a brief discussion of the vanadium-dependent haloperoxidases and model systems. There is also some discussion of vanadium in the environment and of some technological applications. Because vanadium pollution is inextricably linked to vanadium(V) chemistry, some discussion of vanadium as a pollutant is provided. This book provides only a very brief discussion of vanadium oxidation states other than V(V) and also does not discuss vanadium redox activity, except in a peripheral manner where required. It does, however, briefly cover the catalytic reactions of peroxovanadates and haloperoxidases model compounds. 

In the uncharged all-trans complex 588 (entry 9), which may be also considered as a zwitterionic species, the heteroligands are O-bonded in a monodentate fashion to Sn that resides on a crystallographic center of inversion [Sn—O(S) 2.274, Sn—O(P) 2.119 A, cis-angles = 87-93°]1276. A similar zwitterionic structure was found for Me2Sn(OPPh3)[N(SC>2Me)2]2 (entry 10), where the dimesylamide groups act as...
