Abstract: In the title coordination polymer, [Cu(HIDC)(1,10-phen)]_n (HIDC^2- is the 4-carboxyimidazole-5-carboxylate dianion, C₅H₂N₂O₄^2-, and 1,10-phen is 1,10-phenanthroline, C₁₂H₈N₂), the Cu^II atom shows a distorted octahedral coordination configuration, defined by two N atoms from a terminal 1,10-phen molecule, two N atoms and two O atoms from two individual HIDC^2- groups. Adjacent Cu^II atoms are bridged by HIDC^2- groups, forming a one-dimensional chain structure. The CuCu separation within the polymer is 6.132 (4) Å. The chains are linked into a two-dimensional supramolecular network via - stacking interactions.
