New Schiff base (L), derived from condensation of 1,1’-oxalyldiimidazole with o-phenylenediamine has been prepared. Five new
oxovanadium(IV) complexes (one is [VO(L)]SO4 and four [VO(mac)]SO4) have been carried out by using in situ method of preparation
where vanadyl ion act as kinetic template for the Schiff bases. The synthesized complexes were characterized by elemental analyses,
conductometric measurements, magnetic moments, IR, ESR and electronic spectroscopy. These complexes contain VO2+ group and have
square pyramidal geometry wherein Schiff bases act as tetradentate chelating ligands.
Key words: Schiff base, 1,1’-oxalyldiimidazole, oxovanadium(IV), chelating legends
