catena-Poly[cadmium(II)-μ-benzene-1,2-diamine-κ2 N:N′-di-μ-chlorido]

The title compound, [CdCl2(C6H8N2)]n, is a coordination polymer prepared by the hydrothermal reaction of cadmium chloride and o-diaminobenzene. The cadmium cation, located on an inversion center, is octahedrally coordinated by four Cl atoms at equatorial sites and two N atoms from two ligands at the axial sites. Cd atoms are bridged by Cl atoms, forming extended chains parallel to [010]. Neighboring chains are connected by N—H⋯Cl hydrogen bonds.
