In the title compound, [Cd(C8H4O4)(C12H9N3)]n, each CdII ion is six-coordinated in a distorted octahedral geometry by four carboxylate O atoms from two benzene-1,4-dicarboxylate anions (L), and two N atoms from one 2-(2-pyridyl)benzimidazole ligand. The neighboring CdII ions are bridged by the L ligands, forming a zigzag polymeric chain structure. The chains are further extended into a three-dimensional supramolecular structure through intermolecular N—H⋯O hydrogen bonds.
