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).H2O, 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, 1,446 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.
在室温下,分别将醋酸铜与1,2,4-三唑和苯并三唑的混合物充分研磨,会引发固态反应。结果发现,研磨过程中有醋酸流出。杂环配体1,2,4-三唑或苯并三唑取代了醋酸根并与Cu(II)配位,形成混合配体配合物。元素分析结果表明,产物的组成分别与Cu(C₂H₂N₃)(Ac)·H₂O和Cu(C₆H₄N₃)(Ac)·H₂O一致。两种配合物的红外光谱均显示出杂环配体的C=N振动特征[Cu(C₂H₂N₃)(Ac)·H₂O,1513 cm⁻¹;Cu(C₆H₄N₃)(Ac)·H₂O,1446 cm⁻¹]、醋酸根的C=O[Cu(C₂H₂N₃)(Ac)·H₂O,1570和1406 cm⁻¹;Cu(C₆H₄N₃)(Ac)·H₂O,1604和1422 cm⁻¹]以及水的O-H(-3400 cm⁻¹)的特征。固态反应为合成新配合物提供了一种快速、温和且无溶剂的方法。
