The topic, vanadium nitrogenase, is reviewed with respect to biological cha
racteristics and findings on its structure and functions. Structural models
(vanadium complexes containing ligands related to the active center in the
iron-vanadium cofactor) and functional models for the reductive protonatio
n of dinitrogen, the activation of alkynes and reductive C-C coupling of is
ocyanides are addressed. (C) 2000 Elsevier Science Inc. All rights reserved
