A novel triple-stranded cadmium(II) polymer chain: catena-poly[cadmium(II)-mu-1,2-bis(imidazol-1-yl)ethane-kappa N-2(3): N-3 '-di-mu-1,5-dicyanamido-kappa N-4(1): N-5]

In the crystal structure of the title complex, [Cd(C2N3)(2)(C8H10N4)](n) or [Cd(dca)(2)(bim)](n), where dca is dicyanamide and bim is 1,2-bis(imidazol-1-yl)ethane, each Cd-II atom is in a distorted octahedral environment. Four N atoms from four dca ligands occupy the equatorial positions, and two N atoms from two bim ligands occupy the axial positions. Each Cd-II atom is situated at a center of symmetry, and a twofold axis runs through the mid-points of the bim exocyclic C-C bond and the Cd center dot center dot center dot Cd vector. The structure consists of chains in which neighboring Cd-II atoms are connected through one bim and two end-to-end dca bridges.
