摘　　要：制备了由2,6—二乙酰吡啶和肼基硫代甲酸酯衍生的希夫碱C_5H_3N[CH=NNHC(S)XR]_2(X=S,R=CH_3、C_6H_5CH_2;X=O,R=C_6H_5CH_2).离析出类型为MC_5H_3N[CH=NN=C(S)XR]_2(M=Co^(2+)、Ni^(2+)、Zn^(2+)、Pb^(2+)和Cd^(2+))的希夫碱配合物.配合物为元素分析、红外、可见—紫外光谱以及磁化率测量所表征.结果指出:上述希夫碱均为N_3S_2型五齿配体.The SchifT bases 2,6-C5H3N(CH = NNHC(S)XR)2(whcre X = S, R = CH3, C6H5CH2; and X = O, R = C6H5CH2) derived from 2,6-diacetylpyridine and dithiocabazatc have been prepared. Complexes of the Schiff bases of the type MC,H3N(CH = NN = C(S)XR)2(M = Co2+, Ni2+, Zn2+, Pb2+ and Cd2+) have been isolated. The complexes were characterized by elemental analysis, infrared and visible-ultraviolet spcctroscopy and magnetic susceptibility measurements. The results denote that the Schiff bases are pcnta-dcntatc ligands of N3S2-type.
