The centrosymmetric molecule of the title complex, [Cd4Cl8(C3H4N2)6(C3H7NO)2], contains four CdII atoms, six imidazole, two dimethylformamide and eight chloride ligands. The structure shows a novel chloride-bridged tetranuclear cadmium quasi-cubane cluster. The coordination geometry of all CdII atoms is distorted octahedral, with the two metal atoms in the asymmetric unit in different coordination environments. One of the Cd2+ ions is coordinated by five Cl− ions and by one N atom from an imidazole ligand, while the second is coordinated by three chloride ligands, two N atoms from two imidazole ligands and one O atom from a dimethylformamide molecule. Intermolecular N—H...Cl hydrogen bonds link the molecules into a two-dimensional polymeric structure parallel to the ab plane.
