Synthesis, Thermal and Spectral Study of Oxovanadium(IV) Complexes with Benzoic Acid Hydrazine and p-Hydroxybenzoic Acid Hydrazide

Abstract

A series of new oxovanadium(IV) complexes with benzoic acid hydrazide and p-hydroxybenzoic acid hydrazide have been prepared and characterized. Studies of the chemical and physical properties of these complexes were carried out using I.R. and electronic spectroscopy along with conductivity, magnetic susceptibility and thermogravimetric measurements. It was found that depending on the reaction conditions two types of complexes have been obtained with 1:1 and 2:1 L:M stoichiometry with the general formula being VO(L) X.nHzO (X = SO₄- and 2Cl-; L = BH and p-HBH) or VOLz, respectively.
