A new series of five complexes of oxovanadium(IV) with the general formula [VO(mac)]SO4 (where mac = tetraazamacrocyclic ligands
derived by condensation of 1,1’-oxalyldiimidazole with 1,2-diaminopropane and their reactions with β-diketones) have been prepared using
oxometal ion as kinetic template. The prepared complexes have been characterized on the basis of electrical conductance, molecular
weight, magnetic moment, elemental analyses, infrared, e.s.r. and electronic spectral data. The probable coordination number of central
metal is five (distorted square-pyramid).
Key words: oxovanadium(IV), amines, kinetic template, macrocyclic complexes
