A novel two-dimensional Cd coordination framework, poly[[μ-1,3-bis(2-methyl-1H-imidazol-1-yl)benzene-κN:N'cadmium(II)] dihydrate], {[Cd(CHO)(CHN)]·2HO} or {[Cd(PDA)(1,3-BMIB)]·2HO} [1,3-BMIB is 1,3-bis(2-methyl-1H-imidazol-1-yl)benzene and HPDA is 1,3-phenylenediacetic acid], has been prepared and characterized using IR, elemental analysis, thermal analysis and single-crystal X-ray diffraction, the latter revealing that the compound is a (4,4) grid coordination polymer with layers oriented parallel to the bc crystal planes. In the crystal, adjacent layers are further connected by O-H...O and C-H...O hydrogen bonds, forming a three-dimensional structure in the solid state. In addition, the compound exhibits strong fluorescence emissions and shows photocatalytic activity for the degradation of methylene blue in the solid state at room temperature.
一种新型二维镉配位框架，聚[[[μ - 1,3 - 双(2 - 甲基 - 1H - 咪唑 - 1 - 基)苯 - κN:N'](μ - 1,3 - 苯二甲酸二乙酯 - κO,O':O'',O''')镉(II)]二水合物]，{[Cd(CHO)(CHN)]·2HO} 或 {[Cd(PDA)(1,3 - BMIB)]·2HO} [1,3 - BMIB 是 1,3 - 双(2 - 甲基 - 1H - 咪唑 - 1 - 基)苯，HPDA 是 1,3 - 苯二甲酸]，已通过红外光谱、元素分析、热分析和单晶 X 射线衍射进行了制备和表征，后者表明该化合物是一种(4,4)网格配位聚合物，其层平行于 bc 晶面取向。在晶体中，相邻层通过 O - H...O 和 C - H...O 氢键进一步连接，在固态下形成三维结构。此外，该化合物表现出强烈的荧光发射，并在室温下固态时对亚甲基蓝的降解显示出光催化活性。
