Single-crystal X-ray diffraction analysis of poly[bis(μ2-5-carboxy-2-propyl-1H-imidazole-4-carboxylato-κ(3)N(3),O(4):O(5))copper(II)], [Cu(C8H9N2O4)2)]n, indicates that one carboxylic acid group of the 2-propyl-1H-imidazole-4,5-dicarboxylic acid (H3PDI) ligand is deprotonated. The resulting H2PDI(-) anion, acting as a bridge, connects the Cu(II) cations to form a two-dimensional (4,4)-connected layer. Adjacent layers are further linked through interlayer hydrogen-bond interactions, resulting in a three-dimensional supramolecular structure.
聚[双(μ2 - 5 - 羧基 - 2 - 丙基 - 1H - 咪唑 - 4 - 羧基 - κ(3)N(3),O(4):O(5))铜(II)]，即[Cu(C8H9N2O4)2]n的单晶X射线衍射分析表明，2 - 丙基 - 1H - 咪唑 - 4,5 - 二羧酸(H3PDI)配体的一个羧酸基团去质子化。生成的H2PDI(-)阴离子作为桥连基团，连接Cu(II)阳离子形成二维(4,4)连接层。相邻层通过层间氢键相互作用进一步连接，形成三维超分子结构。
