摘　　要：室温下 ,醋酸铜分别与 1,2 ,4 三氮唑和苯并三氮唑充分研磨 ,能发生固相配位反应 ,研磨过程有醋酸逸出 ,杂氮配体取代了醋酸与Cu (Ⅱ )配位形成混配配合物 ,元素分析表征表明产物的组成为Cu(C2 H2 N3) (Ac)·H2 O和Cu (C6 H4 N3) (Ac)·H2 O。红外光谱图显示了杂氮配体的 CN ,醋酸的 CO 和水的O—H特征吸收。固相反应为合成新配合物提供了一条快速、温和及不需溶剂的途径。At room temperature, sufficiently grinding the mixtures of copper acetate with 1, 2, 4-triazole and benzotriazole separately resulted in the proceeding of the solid state reaction. it was found that the acetate acid flowed during the grinding. The heterocycle ligand 1,2,4-triazole or benzotriazole replaced the acetate and coordinates to Cu (II) to form a mixed ligands complex. The elementary analysis results show that the compositions of products were consistent with Cu (C2H2N3)(Ac) . H2O and Cu (C6H4N3)(Ac) . H2P, respectively. Infrared spectra of both complexes have exhibited the characteristics of C=N vibrations [Cu(C2H2N3)(Ac) . H2O, 1 513 cm(-1); Cu (C6H4N3)(Ac) . H2O, 1446 cm(-1)] for heterocycle ligands, C=O [Cu(C2H2N3)(Ac) . H2O, 1 570 and 1 406 cm(-1); Cu (C6H4N3)(Ac) . H2O, 1 604 and 1 422 cm(-1)] for acetate and O-H (-3 400 cm(-1)) for water, respectively. The solid state reaction provides a way which is rapid, mild and in the absence of solvent for synthesized new complexes.
