制备了由2,6-二乙酰吡啶与肼基硫代甲酯衍生的希夫碱C_5H_3N[CH=NN=C(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=VO~(2+)、Mn~(2+)和Fe~(2+))和FeC_5H_3N[CH=NN=C(S)SR]_2Cl的希夫碱配合物。希夫碱及其配合物为元素分析、红外、可见一紫外光谱以及磁化率测量所表征,结果与所提出的Mn~(2+)、Fe~(2+)及Fe~(3+)配合物的结构一致.在VO(Ⅱ)配合物的情况,则形成多聚体,其结构为: -(N_3S_2)V-O-V(N_3S_2)-O-V(N_3S_2)-.
The Schiff base C_5H_3N [CH = NN = C (S) XR] _2 (X = S, R = CH_3, C_6H_5CH_2) derived from 2,6- diacetylpyridine and hydrazinothiomethyl ester was prepared. R = C_6H_5CH_2). The results show that the type of MC_5H_3N [CH = NN = C (S) XR] _2 (M = VO ~ (2+), Mn 2+ and Fe 2+) and FeC_5H_3N [CH = NN = C S) SR] _2Cl Schiff base complexes. Schiff bases and their complexes were characterized by elemental analysis, IR, UV-Vis and magnetic susceptibility measurements. The results were in agreement with the proposed Mn 2+, Fe 2+ and Fe 3+ In the case of VO (Ⅱ) complexes, multimers are formed, and their structures are: - (N 3 S 2) VOV (N 3 S 2) -OV (N 3 S 2) -.
