| 摘 要： | Three binuclear Nickel(Ⅱ) complexes were synthesized, bridged with dithiooxalate, Ni2(Bpy)3(Dto)2(H2O)3(1), Ni2(Phen)3(Dto)2(H2O)3(2) and Ni2(Me2Bpy)3(Dto)2(H2O)2 (3) (Bpy=2,2′-Bipyridine, Phen=1,10-phenanthroline, Me2Bpy=4,4′-dimethyl-2,2′-bipyridine, Dto2-=Dithiooxalate), and characterized by elemental analyses, IR, UV-Visible spectra, conductance. The variable temperature magnetic susceptibilities for the complexes were measured in the range of temperature between 1.5 K and 298 K. Experimental data of magnetic susceptibility were successfully fit to theoretical value based on the spin Hamiltonian operator：(?), S1=S2=1, giving the magnetic exchange parameters of 2J=-52.8 cm-1. This result indicates the presence of a strong antiferromagnetic spin exchange interaction between the Ni(Ⅱ) ions. The magnetic exchange parameters of the binuclear Nickel(Ⅱ) complexes bridged with dithiooxalate is larger than that of the binuclear Nickel(Ⅱ) complexes bridged with oxalate. Dithiooxalate is more effective to transfer antiferromagnetic spin exchange interaction between the Ni(Ⅱ) ions than oxalate.
