Abstract: In the title one-dimensional coordination polymer, [Cd(HIDC)(1,10-phen)]_n (where HIDC^2- is the imidazole-4,5-dicarboxylate dianion, C₅H₂N₂O₄^2-, and 1,10-phen is 1,10-phenanthroline, C₁₂H₈N₂), the Cd^II atom has a distorted octahedral coordination geometry, defined by two N donors from a chelating 1,10-phen molecule, two N-atom donors and two O-atom donors from two individual HIDC^2- groups. Adjacent Cd^II ions are bridged by HIDC^2- groups, resulting in a one-dimensional chain structure. The CdCd separation within the polymer is 6.661  (2)  Å. The chains are linked into a two-dimensional supramolecular network via - stacking interactions.
