catena-Poly[[[1,2-bis-(benzimidazol-2-yl)ethane]cadmium(II)]-μ-sebacato].

In the title compound, [Cd(C(10)H(16)O(4))(C(16)H(14)N(4))](n), the Cd(II) ion is six-coordinated in a distorted octa-hedral geometry by four carboxyl-ate O atoms from two sebacate ligands and two N atoms from the chelating 1,4-bis-(2-benzimidazol-yl)ethanebutane ligand. Neighboring Cd(II) ions are bridged by the sebacate ligands, forming a zigzag polymeric chain structure. The chains are further extended into a three-dimensional supra-molecular structure through inter-molecular N-H⋯O hydrogen bonds.
