Single‐crystal X‐ray diffraction analysis of polybis(μ2‐5‐carboxy‐2‐propyl‐1H‐imidazole‐4‐carboxylato‐κ3N3,O4:O5)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 CuII 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.
