以H4 HmIDC为起始原料，在溶剂热条件下合成了两种新的碱土金属配位聚合物[Ba（H2 IDC）-（H3 HmIDC）（H2O）2]n（I）和[Sr（H2 HmIDC）]n（II）[H3 IDC = 1H-咪唑-4，5-二甲酸，H4 HmIDC = 2-（羟甲基）-1H-咪唑-4，5-二甲酸].化合物I和II均通过不同技术进行结构表征，例如单晶X射线衍射（CIF文件CCDC nos. 1839705（I）和1839706（II））、FT-IR光谱、粉末X射线衍射和热重分析。化合物I显示了一个二维（2D）配位网络，具有基于双核[Ba 2 O 4]作为第二构建单元（SBU）的（4，4）拓扑结构。而化合物II具有基于无限1D无机链作为SBU的3D配位框架，其可以进一步简化为5连接的noy拓扑结构。此外，还研究了化合物I和II的光致发光性质。
Two new alkaline earth metal coordination polymers, which are [Ba(H2IDC)-(H3HmIDC)(H2O)2]n (I) and [Sr(H2HmIDC)]n (II) [H3IDC = 1H-imidazole-4,5-dicarboxylic acid, H4HmIDC = 2-(hydroxymethyl)-1H-imidazole-4,5-dicarboxylic acid), respectively, have been successfully synthesized under solvothermal conditions by employing H4HmIDC as the starting material. Both compounds I and II were structurally characterized by diverse techniques, such as single crystal X-ray diffraction (CIF files CCDC nos. 1839705 (I) and 1839706 (II)), FT-IR spectra, powder X-ray diffraction, and thermogravimetric analyses. Compound I exhibits a two-dimentional (2D) coordination network with a (4, 4) topology based on dinuclear [Ba2O4] as second building units (SBUs). Whereas compound II features a 3D coordination framework based on infinite 1D inorganic chains as SBUs, which can be further simplified as a 5‑connected noy topology. In addition, the photoluminescent properties of both compounds I and II were also investigated.
