catena-Poly[2-methyl-1H-imidazol-3-ium [(aqua-chloridocadmate)-di-μ-chlorido]].
The asymmetric unit of the title compound, {(C(4)H(7)N(2))[CdCl(3)(H(2)O)]}(n), contains one 1-methyl-1H-imidazol-3-ium cation, one Cd(II) atom, three Cl atoms and one water mol-ecule. Adjacent Cd ions are inter-connected alternately by paired Cl(-) bridges to generate an infinite one-dimensional coordination chain along the b axis. In the chain, the crystallographically unique Cd(II) atom, with a distorted octa-hedral geometry, is coordinated by five Cl(-) ions and one water mol-ecule. Intra-chain O-H⋯Cl hydrogen bonding and N-H⋯Cl hydrogen bonding between the cations and the anionic chains consolidate the crystal packing.
