合成了不对称双Schiff碱（H3L）Cu（Ⅱ）单核配合物HCuL（H3L=N-（3-羧基水杨醛）-N’-（5-氯水杨醛）缩乙二胺）和异金属三核配合物（CuL）2Mn，并通过IR谱、电子光谱、元素分析等方法对其进行了表征，其组成为Cu2MnC34H26O9N4Cl2；在5-300K温度范围，测定了这些三核配合物的变温磁化率，并拟合了测定结果，表明这些化合物金属离子间均为反铁磁耦合，磁耦合因子J=-9．24cm^-1．

A asymmetrical double Schiff base （H3L） Cu（Ⅱ） mononuclear complex：HCuL （Where H3L is N - 3 - carboxylsalicylidene - N＇ - 5 - chlorosalicylaldehyde - 1,2 - diamino ethane） and heterometal trinuclear complex （（CuL） 2Mn） with the chemical formula Cu2MnC34H26O9N4Cl2 have been synthesized and characterized by means of elemental analyses, IR and electronic spectra. The magnetic property of the heterotrinucler complex have been determined in the temperature range 5 - 300K,which indicate that the interaction between the central Mn^2＋ ion and the outer Cu^2＋ ions is antiferromagnetic. The exchange integral J is equal to -9.24cm^-1.
