The oxovanadium(IV) complexes of the Schiff bases derived from 1,3‐diamino‐propane‐2‐ol and salicylaldehyde, 3‐aldehydosalicylic acid, 5‐chloro‐salicylaldehyde, acetyl acetone, and also of the Schiff base derived from 1.3‐diaminopropane and salicylaldehyde have been isolated in the pure state and characterized. The structure of these complexes is discussed on the basis of elemental analyses, electronic spectra and magnetic moment values. These complexes are characterized as five co‐ordinate compounds having the general formula [VO](L), where, LH 2 = a molecule of dibasic, tetradentate Schiff base. Electronic spectra of the complexes are found to be solvent independent. The compounds are paramagnetic (μ eff . = 1.76–1.79 B. M.), and are very stable in air.
