CHEMISTRY OF VANADIUM AND MOLYBDENUM COMPLEXES - SOME RESULTS AND FUTURE-PROSPECTS

The chemistry of the coordination compounds of vanadium and molybdenum is topical due to their involvement in processes of biological import ance. Both of them exhibit a number of oxidation states and form a wid e variety of mono- and binuclear complexes with ligands containing sev eral donor atoms. Using the multidentate ligands and biologically impo rtant imidazole and its derivatives, a large number of complexes have been synthesised and characterised by several techniques including EPR and NMR spectroscopy and electrochemical techniques. These techniques will assume a greater relevance in future providing challenges and op portunities in investigating the chemistry of vanadium and molybdenum and may highlight future prospects.
