Metal-Catalyzed Oxygenation Mechanisms

The vanadium(IV) octaco-ordinated complex (NH4+)[N(CH3)4+][V(HIDA)2](HIDA =N-hydroxy-iminodiacetate), whose anion is a likely model for the natural compound 'amavadin,' has been prepared and its crystal and molecular structures have been determined by X-ray crystallography; this is the first example of an octaco-ordinated vanadium(IV) complex with just N and O donor atoms.
