Formation of Cu [II] -sulphato schiff base complexes spectral and magnetic studies

ABSTRACT

Cu[II]-sulphato Schiff base complexes of the type [Cu [SB]SO[4]]2H[2]O or [Cu[SB]SO[4] [H[2]O][2]],where [SB] is bidentate or tetradentate Schiff s base, were synthesized and characterized by elemental analysis, conductance measurement IR, electronic and electron paramagnetic resonance spectra as well as magnetic moments determination. Generally, the spectral results showed that Cu[II] ions are present in an axial elongated symmetry [D[4h]]. Moreover, the magnetic moment values [<1.74 B.M.] measured at room temperature and the g values suggest the presence of an appreciable metal - metal interaction
