Abstract: | Three Schiff base ligands and their corresponding copper(II) complexes have been prepared and characterized. Elemental analyses, mass spectra, i.r., electronic spectra, eff and the X- ray crystal structure for one of the complexes, as well as elemental analyses, mass spectra, i.r., electronic and 1H n.m.r. spectra of the ligands, have been obtained. The X-ray study shows that the geometry around the metal atom is intermediate between square planar and tetrahedral. Electrochemical studies on the complexes reveal a dependence of the CuII/CuI potentials on the extent of distortion of the planar structure observed in solid state. |
