| Abstract: Two new trinuclear copper(Ⅱ) complexes bridged with N,N′-Bis(2-pyridylmethyl)-Dithiooxamidate, ［Cu3L2］(ClO4)2(1) and ［Cu3L2］(NO3)2(2) (H2L=N,N′-Bis(2-pyridylmethyl)-Dithiooxamide), have been synthesized, and characterized by elemental analyses, IR, UV-visible spectra, conductance and EPR spectra. The variable temperature magnetic susceptibility for complex (1) has been measured in the range of 1.5～298K. Experimental data of magnetic susceptibility are successfully fit to theoretical value based on the spin Hamiltonian operator: H=-2J(S1S2+S2S3)-2J′S1S3, S1=S2=S3=1/2, giving the magnetic exchange parameters of 2J=-170 cm-1 and 2J′=-7.2 cm-1. This result indicates the presence of a strong antiferromagnetic spin exchange interaction between the Cu(Ⅱ) ions. |
