Synthesis and characterization of oxovanadium [IV] Schiff base complexes: spectral, magnetic and thermal studies

A series of new complexes of oxovanadium [IV] with Schiff bases derived from some aromatic diamines and 2-hydroxynaphthaldehyde was prepared and characterized by elemental analysis, spectral, conductance as well as by magnetic moment measurements. The oxovanadium [IV] complexes formed monomeric or dimeric complexes by ligand bridging. The structures of the complexes were found to depend on the position of the imine group link to the aromatic moiety. The reaction of oxovanadium [IV] complexes with thionyl chloride was also studies. Thermal analysis of some of the prepared complexes was discussed
