Tetradentate Schiff base ligand (L), derived from condensation of 1,1’-oxalyldiimidazole with 1,3-diaminopropane 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. Here vanadyl ion acts as kinetic template for the Schiff bases. The prepared vanadium complexes were characterized by elemental analysis, conductometric measurements, magnetic moments, IR, ESR and electronic spectroscopy to investigate the tentative structure. These oxovanadium(IV) complexes contain VO2+ group and have square pyramidal geometry wherein Schiff bases act as tetradentate chelating ligands
