Abstract: In the centrosymmetric title complex, [Cd₂(C₇H₄ClO₂)₄(C₃H₄N₂)₄]·2H₂O, each Cd^II atom is coordinated by five carboxylate O atoms from three 4-chlorobenzoate ligands and two N atoms from two imidazole ligands, displaying a distorted pentagonal-bipyramidal geometry. The dinuclear molecules, with a CdCd separation of 3.868 (3) Å, form a supramolecular network via intermolecular hydrogen bonds and - stacking interactions. The face-to-face distance between parallel 4-chlorobenzoic acids of neighboring complexes [ at ()] is 3.563 (3) Å. There are also - stacking interactions of imidazoles [at ()], with a centroid-centroid distance of 3.623 (3) Å.
