Abstract

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.
