摘　　要：合成了吡唑-3,5-二(N-烷基甲酰胺)(LH_3)的一系列配合物:(LH_2)_2Cu_2(NO_3)_2·H_2O,L_2Cu_2Na_2·nH_2O。得到了(PEAH_2)_2Cu_2(NO_3)_2·H_2O的单晶结构。(PEAH_3代表吡唑-3,5-二(N-乙基甲酰胺))。从元素分析及红外光谱讨论了不同pH时配合物的配位形式。配合物的ESR谱表明了分子内两个Cu原子间有自旋交换作用。We have synthesized a number of new complexes (LH3)2Cu2(NO3)2·H2O, L2Cu2Na2·nH2O, where LH3 = Pyrazolc-3,5-bis(N-a1kylcarboxyamide). From elemental analysis data and IR spectra, we suggest the formation of neutral amide complexes in neutral solution and the deprotonated amide complexes in high pH solution. The crystal structure of (PEAH2)2Cu2(NO3)2 ?H2O, where PEAH3 = Pyrazole-3,5-bis(N-ethylcarboxyamide), was obtained by X-ray single crystal analysis. The ESR spectra of complexes show that there arc spin-exchange interaction between two copper atoms in the molecules.
