Single‐crystal X‐ray diffraction analysis of poly[bis(μ 2 ‐5‐carboxy‐2‐propyl‐1 H ‐imidazole‐4‐carboxylato‐κ 3 N 3 , O 4 : O 5 )copper(II)], [Cu(C 8 H 9 N 2 O 4 ) 2 )] n , indicates that one carboxylic acid group of the 2‐propyl‐1 H ‐imidazole‐4,5‐dicarboxylic acid (H 3 PDI) ligand is deprotonated. The resulting H 2 PDI − 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.
