Vanadium heterometallic

Few gold compounds contain vanadium-carbonyl fragments or dicyclopentadienyl-niobium fragments, respectively, and no additional interactions between discrete heterometalic cores are present in the crystal of any of them. 

Numerous studies involving similar amido derivatives of metals such as Ti (e.g. heterometallic cross-coupling of benzonitrile with carbon dioxide, pyridine, and benzophenone with mixed [Ti N(Bu )Ar 3] and [Mo N(Bu )Ar 3] systems), V (e.g. denitrogenation of a vanadium nitride by carbon disulfide and dioxide), Nb (e.g. the... 

Synthetic structural models for clusters within the nitrogenase proteins or of the molybdenum or vanadium iron - sulphur cofactors isolated from them, are at an eaily stage of development and there are as yet no well - defined systems which model electron - transfer chemistry involving the binding and reduction of molecular nitrogen or other substrates dinitrogen binding to synthetic iron - sulphur clusters or heterometallic iron - sulphur clusters of any type has not been established structurally nor spectroscopically, [44- 46].

A vanadium(v)-molybdenum(vi) heterometallic oxo-alkoxide [V2Mo2(0)g (0Me)2 (0CH2)3C(CH20H) 2] has also been characterized. The V2M02O16 core involving octahedral metals is reminiscent of the Ti40ie core of titanium tetraUcoxides. ...
