The title complex, Cu(2)Br(3)(C(11)H(9)N(2)O(2)), was one of three isolated by slow evaporation of an acetonitrile reaction mixture of CuBr(2) with di-2-pyridyl ketone (1:1 molar ratio). The title complex contains a 2:1 metal-to-ligand ratio of copper(II) with the hydrated form of the ligand, di-2-pyridylmethane-diol. The two copper centers are bridged by a bromide ion and the alk-oxy O atom, and the Cu-Cu distance is 2.9801 (5) Å. The dimeric units are further linked by bromide ions, leading to a two-dimensional extended bridged structure. O-H⋯O hydrogen bonds are present in the crystal structure.
标题配合物[Cu₂Br₃(C₁₁H₉N₂O₂)]ₙ是通过将CuBr₂与2,2'-联吡啶酮(摩尔比1:1)的乙腈反应混合物缓慢蒸发分离得到的三种配合物之一。标题配合物中铜(II)与配体水合形式2,2'-二吡啶甲烷二醇的金属与配体比例为2:1。两个铜中心由一个溴离子和烷氧基O原子桥联,Cu-Cu距离为2.9801(5) Å。二聚单元通过溴离子进一步连接,形成二维扩展桥联结构。晶体结构中存在O-H⋯O氢键。
