摘　　要：合成了五个2,6-二乙酰吡啶缩肼基硫代甲酸酯双希夫碱合铜(Ⅱ)配合物,用元素分析、磁化率、红外光谱及紫外-可见光谱等对它们进行了表征,研究了配合物的电化学性质和Cu_3L_2~2X_2(X=Cl^-、SCN^-)的光电子能谱。结果表明:五个Cu(Ⅱ)配合物均为三核配合物,在Cu_3L_2~2(SCN)_2中存在Cu(Ⅱ)间的自旋—交换作用。The Schiff bases 2,6-C5H3N(CH = NNHC(S)XR)2 (where X = S, R = CH3, C6H5CH2) de-rived from 2,6-diacetylpyridine and dithiocarbazate have been prepared. Five Cu(II) com-plexes of the Schiff bases which are Cu3L2Cl2, Cu3L2Br2, Cu3L2Cl2, Cu3L22Br2 and Cu3L22(SCN)2 have been isolated. The complexes were characterized by elemental analysis, infrared and visible-ultraviolet spectroscopy and magnetic susceptibility measurements. The electrochemical properties of the complexes and the XPS of Cu3L22Cl2 and Cu3L2(SCN)2 were investigated. The results denote that five Cu(II) complexes all are trinuclear compounds and Cu3L22(SCN)2 present spin-exchange reactions between several Cu(II) states.
