摘　　要：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。Copper（ Ⅱ ） complex [Cu3（μ-OH）（μ-pz）3（Hpz）（μ-Ac）2]n is synthesized by self-assembly using pyrazole and cop- per acetate in the solution with pH 9 at room temperature. The structure of the complex is confirmed by elemental analysis and X- ray single-crystal diffraction. The results shows that the crystal belonged to monoclinic system with P2 （1）/c space group, and the cellparameter：a=1l.648（2） A°,b=19.869（3） A°,c=9.703 5（16） A°,β=99.535（2）°. All of the three coppers within the complex performance tetrahedral configuration. The hydroxide is bonded to the three copper ions. The helix chain is formed by bridging ligands and which is further linked by acetate.
