Abstract: The title compound, [Cd₂Cl₄(C₁₂H₉N₃)₂], was prepared under hydrothermal conditions. In the centrosymmetric dimeric molecule, two Cd^II atoms are bridged by two Cl atoms. One terminal Cl atom and two N atoms from a bidentate chelating 2-(2-pyridyl)benzimidazole ligand complete a distorted square-pyramidal geometry around each Cd^II atom. A three-dimensional network is constructed via intermolecular N-HCl and weak C-HCl hydrogen bonds, as well as - interactions between adjacent ligands with a centroid-to-centroid distance of 3.49 (1) Å between the benzimidazolyl and pyridyl groups and a centroid-to-centroid distance of 3.54 (1) Å between the imidazolyl rings.
