Abstract
Oxovanadium(IV) complexes of aroyl hydrazone Schiff bases, viz. salicy loyl, nicotinoyl and benzoyl hydrazones, have been synthesized and cha racterized by elemental analysis, spectroscopy (IR and UV-vis) methods , magnetic susceptibility, EPR measurements, molar conductance and cyc lic voltammetry studies. The room-temperature magnetic moments of the complexes are in the range 0.97-1.03 B.M. and are indicative of the pr esence of anti-ferromagnetic exchange. A binuclear structure has been proposed for the complexes. (C) 1997 Published by Elsevier Science Ltd .
