在热甲醇水溶液中,2,2′-联吡啶(2,2′-bpy),醋酸铜和溴化钠经回流反应合成了三重桥联双核铜新化合物——[Cu2(μ-O2CCH3)(μ-OH)(μ-Br)(2,2′-bpy)2]Br.2H2O(1),其结构经IR,元素分析和X-射线单晶衍射表征。1属三斜晶系,P-1空间群,晶胞参数:a=7.561 7(12),b=12.364 7(18),c=14.611 0(2),α=95.963(3)°,β=101.815(3)°,γ=104.374(2)°,V=1 277.9(3)3,Z=2,Dc=1.849 g.cm-3,μ=4.831 mm-1,F(000)=704,R1=0.063 2,wR2=0.171 6。1通过氢键和分子间π┈π堆积相互作用,连接成三维网状结构。

A novel triply-bridged binuclear copper（ Ⅱ ） complex, [Cu2（μ-O2CCH3）（μ-OH）（μ-Br）（2,2＇-bpy）2]Br·2H2O （ 1 ）, was synthesized by reflux recaction of 2,2＇-bipyridine （2,2＇-bpy）, copper acetate and sodium bromide in ethanol/water solution. The structure was characterized by IR, elemental analysis and single-crystal X-ray diffraction analysis. 1 belongs to triclinic, space group P-1 with a=7.561 7（12） A, b=12.3647（18） A, c=14.611 0（2） A, α=95.963（3）°,β= 101.815（3）°, γ=104.374（2）°, V=1 277.9（3） A^3, Z=2, Dc=1.849 g · cm^-3,μ=4.831 mm^-1, F（000） =704, R1 =0.063 2, wR2 =0. 171 6. The three dimensional network of 1 formed via hydrogen bonds and intermolecular π……π stacking interactions.
