摘　　要：在1∶1的乙醇水溶液中,利用配合物作配体的方法,将CuL2-与Cu2+以2∶1的摩尔比回流,制得了具有不对称结构的双Schiff碱配体H3L[H3L=N-(3-羧基水杨醛)-N'-(5-氯水杨醛)缩乙二胺]的Cu均三核配合物CuL-Cu-CuL,并通过元素分析I、R、电子光谱等方法对其进行了表征和性质研究,其组成为Cu3C34H26O9N4Cl2;在5～300 K温度范围,测定了该三核配合物的变温磁化率,拟合表明该三核配合物的Cu-Cu金属离子间为反铁磁偶合,磁偶合因子J=-61.8 cm-1,g=2.21,θ=-4.98 K.Using the method of complex as ligand in 1∶1 ethanol aqueous,the Cu2＋ trinuclear complex（CuL）2Cu with the chemical formula Cu3C34H26O9N4Cl2 and asymmetrical structure double Schiff base N-3-carboxylsalicylidene-N′-5-chlorosalicylaldehyde-1,2-diamino ethane（H3L） has been obtained and characterized by means of elemental analysis,IR spectra and electronic spectra（Where L3-=dehydration of the ligand H3L）.The magnetic property of the heterotrinuclear complex has been determined in the temperature range 5-300 K,which indicates that the interaction between the central Cu2^＋ ion and the outer Cu2^＋ ions is antiferromagnetic.The exchange integral J=-61.8 cm^-1,g=2.21,θ=-4.98 K.
