Abstract

In the title compound, [Cd2I4(C6H14N2)2]n, there are two independent CdII ions. One CdII 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 CdII ion is coordinated by four iodido ligands in a slightly distorted tetrahedral coordination environment. Two of the iodido ligands act as bridging ligands connecting CdII 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).
