catena-Poly[[trans-bis­(cyclo­hexane-1,2-diamine-κ(2) N,N)cadmium]-μ-iodido-(diiodidocadmium)-μ-iodido]

In the title compound, [Cd(2)I(4)(C(6)H(14)N(2))(2)](n), there are two independent Cd(II) ions. One Cd(II) ion is coordinated in a slightly distorted octa­hedral coordination environment by four N atoms from two cyclo­hexane-1,2-diamine ligands and two iodido ligands. The other Cd(II) ion is coordinated by four iodido ligands in a slightly distorted tetra­hedral coordination environment. Two of the iodido ligands act as bridging ligands connecting Cd(II) ions and forming a one-dimensional polymer along [010]. In the crystal, N—H⋯I hydrogen bonds connect the one-dimensional structure into a two-dimensional framework parallel to (001).
