吡唑与醋酸铜在p H 9的水溶液中,室温下通过自组装合成标题配合物。用元素分析和X-射线单晶衍射分析配合物的结构,结果显示,晶体属于单斜晶系,空间群为P2(1)/c,晶体单胞参数为a=11.648(2),b=19.869(3),c=9.703 5(16),β=99.535(2)°。配合物3个中心铜(Ⅱ)离子均采取四面体构型,氢氧根与3个铜离子均形成配位键,由于配体桥连使配合物形成螺旋链,螺旋链之间通过醋酸根连接。
The pyrazole was combined with copper acetate in an aqueous pH9 solution to synthesize the title complex by self-assembly at room temperature. The structure of the complex was analyzed by elemental analysis and single crystal X-ray diffraction. The results show that the crystal belongs to the monoclinic system with the space group P2 (1) / c, the unit cell parameters a = 11.648 (2) and b = 19.869 (3) , c = 9.703 5 (16) , β = 99.535 (2) °. The three central copper (Ⅱ) ions of the complexes all adopt the tetrahedron configuration, and both the hydroxyl and the three copper ions form coordination bonds. Since the ligand bridges the complex to form a helical chain, the helical chains pass between the acetate groups connection.
