    Abstract:
    The title complex, [CdCl(NCS)(C10H8N2)]n, represents an unusual Cd(II) coordination polymer constructed by two types of anionic bridges and 2,2'-bipyridyl (bipy) terminal ligands. These two types of bridges are arranged around inversion centers. The distorted octahedral coordination of the Cd(II) center is provided by two chloride ions, one N- and one S-donor atom from two thiocyanate ions, and a pair of N atoms from the chelating bipy ligand. Interestingly, adjacent Cd(II) ions are interconnected alternately by paired chloride [Cd...Cd = 3.916 (1) A] and thiocyanate bridges [Cd...Cd = 5.936 (1) A] to generate an infinite one-dimensional coordination chain. Furthermore, weak interchain C-H...S interactions between the bipy components and thiocyanate ions lead to the formation of a layered supramolecular structure.
