摘要 合成了不对称双Schiff碱Cu(Ⅱ)单核配合物HCuLe(H3Le为N-3-羧基水杨醛-N-(′5-氯水杨醛)缩乙二胺)及三核配合物Cu(Ⅱ)Co(Ⅱ)Cu(Ⅱ)和Cu(Ⅱ)Cu(Ⅱ)Cu(Ⅱ),用元素分析、红外光谱、电子光谱测试技术对它们进行了表征。测定了2个三核配合物在5-300 K范围内的变温磁化率,并通过自旋哈密顿算符=-2J M(Cu1+Cu2)推导出的理论公式对实验值进行最佳拟合,得到了2个三核配合物的磁交换参数J1=-15.1 cm^-1,J2=-61.8 cm^-1,表明在这2个配合物分子内存在金属离子间反铁磁偶合作用。 An asymmetrical double Schiff base Cu( Ⅱ ) mononuclear complex HCuLe (Where H3Le is N-3- carboxylsalicylidene-N'-(5-chlorosalicylaldehyde-1,2-diaminoethane) ) and its trinuclear complexes Cu( Ⅱ ) M( Ⅱ )Cu( Ⅱ )(M = Co, Cu) were synthesized and characterized by means of elemental analysis, IR and electron spectrometries. The variable-temperature magnetic susceptibilities of (CuLe)2 Co H2O and (CuLe) 2Cu · H2O at 5 - 300 K were analyzed by means of the Hamihonian H^ = - 2JS^M ( S^Cul + S^Ca2 ) , leading to J1 = - 15. 1 cm^-1 , J2 = -61.8 cm^-1 , which indicated that the interaction between the central M( Ⅱ ) ion and the terminal Cu ( Ⅱ ) ions was antiferromagnetical.
