The coordination polymer of copper(I) iodide Cu4I4(DABCO)2 (DABCO = 1,4-diazabicyclo-[2.2.2]octane) was prepared by solvothermal methods, and its structure was determined by single-crystal X-ray diffraction. The structure contains a novel 654 topology and displays interesting self-penetration.
The design and synthesis of inorganic–organic hybrid materials with novel topologies and structural motifs are of current interest in the field of coordination chemistry for their potential application as functional materials.1 Over the past decades, several classes of coordination polymers have been synthesized and investigated. Among these types of polymeric compounds reported so far, copper halides have been widely investigated due to their rich photoluminescent properties and intriguing topology. A series of copper halides in one, two, or three dimensions have been successfully synthesized such as rhomboid dimers of stoichiometry
[Cu2X2L2]n, the tetranuclear species on cubane or stepped cubane tetramers of stoichiometry [Cu4X4L4]n and hexagonal [Cu6X6]n grid chains.2 The main strategy in crystal engineering is a secondary building block approach.3 For a given building block, there are two routes to construct frameworks. One is to form
frameworks with a new topology and the other is to expand the frameworks of some reported inorganic dense materials by replacing the original structure units with larger structure units.
The hydro(solvo)thermal reaction, which is considered the most effective approach to synthesizing crystals, is widely used in preparing coordination polymers. Although the mechanism of the
hydro(solvo)thermal reaction is complicated, some factors influencing the final products have been identified, such as reaction temperature, pH value, solvent and anion.4 In our previous investigation
on copper iodide, we successfully prepared zeolite- like copper iodide Cu4I4(DABCO)2-a with novel 66 topology by replacing the secondary building block in zeolite using Cu4I4(DABCO)4in the hydro(solvo)thermal reaction.5 In Cu4I4(DABCO)4, one Cu4I4 cluster and four DABCO ligands formed a supertetrahedron unit Cu4I4(DABCO)4 with each edg of the supertetrahedron unit about
8 A˚ , which is longer than that of TO4 in zeolites (2.4 A˚ ). To extend our investigation on copper iodide, we changed the copper source to assembly zeolite-like frameworks using the Cu4I4(DABCO)4
supertetrahedron unit as a secondary building unit (SBU). In this short communication, we report the synthesis, structure and some studies on the physical and chemical properties of a zeolite-like microporous compound, Cu4I4(DABCO)2-b, which is an isomer of our previously reported Cu4I4(DABCO)2-a.

具有新的拓扑结构和结构基本图案的无机－有机混合材料的设计和合成在配位化学领域具有现行的意义，因为它们可以潜在地用作功能材料。[1] 在过去几十年间，已经合成和研究过好几类配位聚合物。在迄今报道的这些类型的聚合化合物中，卤化铜一直得到广泛的研究，因为它们具有丰富的光致发光性质和吸引人的拓扑结构。在一维、二维或三维的一系列卤化铜已经成功地得到了合成，比如化学计量法[Cu2X2L2]n的长菱形二聚物、化学计量法[Cu4X4L4]n和六边形[Cu6X6]网格链的在立方烷上的四核类或阶梯式立方烷四聚物。[2] 在晶体工程上的主要策略是一种次级构件途径。[3] 对于一给定的构件来说，有两条构件骨架的路线。一条是用新的拓扑结构形成骨架，另一条是用某些已有报道的无机密致材料扩展骨架，即用较大的结构单元取代原来的结构单元。

被认为是合成晶体最有效途径的水热－溶剂热反应广泛用于制备配位聚合物。虽然水热－溶剂热反应的机理很复杂，但某些影响最终产品的因素，比如反应温度、pH值、溶剂和阴离子的影响已经弄清。[4] 在我们以前对碘化亚铜的研究中，我们一成功制备了具有新的66拓扑结构的类沸石碘化亚铜 Cu4I4(DABCO)2，方法是在水热－溶剂热反应中用 Cu4I4(DABCO)4取代沸石中的次级构件。[5] 在 Cu4I4(DABCO)4中，一个Cu4L4聚类和四个DABCO配体形成了一个超四方体单元 Cu4I4(DABCO)4，超四方体单元的每一个边缘大约为8Å，这比沸石中TO4的（2.4 Å）要长。为了扩展我们对碘化亚铜的研究，我们更改了组合类沸石骨架的铜的来源，采用了 Cu4I4(DABCO)4超四面体单元作为次级构件（SBU）。在本短通讯中我们报道了类沸石微孔化合物[Cu4I4(DABCO)2]-b的合成、结构和物理化学性质的某些研究，这种化合物是我们以前报道的[Cu4I4(DABCO)2]-a的异构体。
