The macrocyclic ligands are synthesized by condensation of o-phenylene diamine and 4-4 diamino, diphenyl methane with acetyl acetone in ethanolic medium followed by formation of their complexes with pentavalent vanadium salt of type VO(acac) 2. Ligands and complexes have been characterized with the help of melting point, molecular weight, conductance, TLC determination, element analysis, magnetic moment and electronic, IR, 1 HNMR spectral analysis. On the basis of these studies, four
