| 摘要: 碘化亚铜和4，4′-二联吡啶在溶液中反应的二种方法可制备出标题化合物的2个不同红色晶体，结构表征出两种晶体分别是单斜C2/c(1)和四方I41/acd(2)空间群。在[Cu( μ-I)( μ-4,4-bipy)]n结构中，铜原子是处于与2个碘原子和2个相互扭曲4,4′-二联吡啶中的氮原子的扭曲四面体配位环境中，2个[Cu( μ-I)]2单元和2个桥式4,4′-二联吡啶配体形成1个[Cu2( μ-I)2( μ-4,4-bipy)]2直角单元，4个直角单元经4个4,4′-二联吡啶侧式桥联而形成1个大的八角环，并由此与直角单元相互垂直而形成1个二维框架结构。 |

| Abstract: Two isologous red crystals of the title compound, prepared in two methods from the reaction of CuI and 4,4′-bipyridine (4,4′-bipy) in solution, were structurally characterized with monoclinic C2/c (1) and tetragonal I41/acd(2) space groups. In the structure of [Cu( μ-I)( μ-4,4-bipy)]n, the Cu atom is in a distorted tetrahedral environment with two I atoms and two N atoms of two mutual-twisted 4,4′-bipys. Two [Cu( μ-I)]2 units and two bridging 4,4′-bipy ligands form a [Cu2( μ-I)2( μ-4,4-bipy)]2 rectanglar unit. Four rectanglar units are side-bridged by four 4,4′-bipy spaces to give a large octagonal ring alternately perpendicular to rectanglar unit to form a two-dimensional framework structure.
