摘　　要：利用不对称双Schiff碱配体N-（3-羧基水杨醛）-N’-（5-氯水杨醛）缩乙二胺（H3L）及其Cu（Ⅱ）单核配合物HCuL（L3H，L的脱氢阴离子，氧化数为3）合成了Cu—Ni异金属三核配合物（CuL）Ni（CuL），并通过IR谱、电子光谱、元素分析、热重分析等方法对其进行了表征和性质研究，其组成为Cu2NiC34H27O95N4Cl2；在5-300K温度范围，测定了该异金属三核配合物的变温磁化率，并拟合了测定结果，表明该三核配合物的Cu—Ni金属离子间为反铁磁偶合，磁偶合因子J=-88．7cm^-1，g=2．23．Using the ligand of a asymmetrical double Schiff base N-3-carboxylsalicylidene-N＇-5-chlorosalicyl- aldehyde-1,2-diamino ethane （H3L） and its Cu（Ⅱ） mononuclear complex, HCuL （Where L^3- =dehydration of the ligand H3L）, the heterometal trinuclear complex （CuL）2Ni with the chemical formula Cu2NiC34 H27O9.5 N4Cl2 has been synthesized and characterized by means of elemental analysis, IR spectra, electronic spectra and thermal gravimetric analysis. The magnetic property of the heterotrinuclear complex has been determined in the temperature range of 5 -300 K, which indicates that the interaction between the central Ni^2＋ ion and the outer Cu^2＋ ions is antiferromagnetic. The exchange integral is J = -88.7 cm^-1,g = 2.23.
