Electrochemical and spectroscopic data of unsymmetrical and symmetrical mononuclear oxo-vanadium(IV)salicyldiimine complexes [VO(x,y-Sal)(x0,y0-Sal)Phen)] and [VO(x, y- Sal)(x0, y0-Sal)iPr)], where x, x0 ¼5-H, 5-Br, 5-NO2 and y, y0 ¼4-H, 4-MeO, were prepared and studied. Our results show tetradentate SalPhen or SaliPr coordinated in the equatorial plane. The electrochemical behavior is related to UV–Vis and IR spectra. Electron-withdrawing groups affected vanadium through -acceptor properties of imine and electron-donation groups through - and -donation via phenolic oxygen.
