摘要：

Two new quadridentate sulphur-nitrogen chelating agents have been prepared and characterized. These ligands yield stable complexes of general formulae, M(ONNS).xH2O (M = Ni, Cu, Zn, Cd, Pd and Pt; ONNS-2 = ligand dianion; x = 0, 1 or 2) and M(ONNS)X (M = Co or Fe; X = Cl or AcO). The nickel(II) complexes are diamagnetic and square-planar. Based on magnetic and spectral data a square-planar structure is also assigned to the copper(II) complexes. The iron(III) complexes, Fe(ONNS)Cl are high-spin and five-coordinate. Magnetic and spectral evidence support an octahedral structure for the cobalt(III) complex, Co(ONNS)OAc.
