title: A two-dimensional copper(II) coordination polymer based on 2-propyl-1H-imidazole-4,5-dicarboxylic acid.
abstract: 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.
