摘　　要：在N2气保护下,3-甲酰基-4-羟基苯甲酸甲酯与环己二胺在无水乙醇中缩合反应合成了新型的Schiff碱配体N,N′-双(3-甲酰基-4-羟基苯甲酸甲酯)缩环己二胺,收率为66.7%。该配体与四水合醋酸锰在无水乙醇中反应,并经空气氧化、氯化锂处理得到Mn3+配合物;与三氯化铁、氯化镍在无水乙醇中配位分别得到Fe3+、N i2+配合物。并通过红外光谱、核磁共振、元素分析等测试方法对配体和配合物结构进行了表征。A new schiff base ligand was synthesized by the condensation reaction of methyl 3-formyl-4-hydroxybenzoate with 1,2-diaminocyclohexane under N2 in absolute ethanol.＇ The ligand first reacted with Mn（OAc）2 · 4H2O, and then the mixture was exposed to air and treated by LiCl in absolute ethanol to obtained a Mn（Ⅲ） complex. Two Fe（Ⅲ ） and Ni（Ⅱ） complexes were also prepared by the reaction of the ligand with the corresponding metal chloride salts. The new ligand and the complexes were characterized by elemental analysis, ^1H NMR and IR.
