通过卤化铜与2-氯吡嗪在室温或水热条件下反应，合成了新的铜配位聚合物2[CuX（μ-2-氯吡嗪-N，N '）]（X = Cl（I），Br（II），1[CuI（2-氯吡嗪-N）]（III）和[Cu 2 I2（2-氯吡嗪）]（IV）. 1：1化合物I和II的晶体结构由平行于晶体学a轴延伸的锯齿形CuX单链组成，其通过2-氯吡嗪间隔分子连接至平行于（010）的片。对于碘化合物III的一维结构被发现，它由CuX双链平行于晶体学a轴运行。所有化合物的热性质进行了研究，在不同的气氛中使用同时差热分析和热重分析（DTA-TG）以及温度分辨X射线粉末衍射。在加热时，1：1的化合物I和II直接分解为相应的卤化铜（I），而III的热分解通过作为中间体的IV发生。
The new copper coordination polymers 2[CuX(μ-2-chlor-opyrazine-N, N')] (X = Cl (I), Br (II), 1[CuI(2-chloropyrazine-N)] (III) and [Cu2I2(2-chloropyrazine)] (IV) has been prepared by the reaction of the copper(I) halides with 2-chloropyrazine at roomtemperature or under hydrothermal conditions. The crystal structures of the 1:1 compounds I and II consist of zig-zag CuX single chains running parallel to the crystallographic a-axis which are linked by the 2-chloropyrazine spacer molecules to sheets parallel to (010). For the iodine compound III a one-dimensional structure is found which consists of CuX double chains running parallel to the crystallographic a-axis. The thermic properties of all compounds were investigated in different gas atmospheres using simultaneously differential thermal analysis and thermogravimetry (DTA-TG) as well as temperature resolved X-ray powder diffraction. On heating, the 1:1 compounds I and II decompose directly to the corresponding copper(I) Halides, whereas the thermal decomposition of III occcur via IV as an intermediate.
