چکیده
The asymmetric unit of the polymeric title compound, {[Cd(NCS)2(C6H6N2S)]·2CH3OH} n , consists of one cadmium(II) cation that is located on a centre of inversion as well as one thio-cyanate anion, one pyridine-4-carbo-thio-amide ligand and one methanol mol-ecule in general positions. The Cd(II) cations are octa-hedrally coordinated by the pyridine N atom of two pyridine-4-carbo-thio-amide ligands and by the S and N atoms of four thio-cyanate anions and are linked into chains along [010] by pairs of anionic ligands. These chains are further linked into layers extending along (201) by inter-molecular N-H⋯O and O-H⋯S hydrogen bonds. One of the amino H atoms of the pyridine-4-carbo-thio-amide ligand is hydrogen-bonded to the O atom of a methanol mol-ecule, and a symmetry-related methanol mol-ecule is the donor group to the S atom of another pyridine-4-carbo-thio-amide ligand whereby each of the pyridine-4-carbo-thio-amide ligands forms two pairs of centrosymmetric N-H⋯S and O-H⋯S hydrogen bonds. The methanol mol-ecules are equally disordered over two orientations.

In the crystal structure of the title complex, [Cd(NCS)(2)(C(7)H(5)ClN(4))(2)](n), the Cd(II) atom lies on a crystallographic inversion center and assumes a distorted octa-hedral geometry. The 2-chloro-6-(1H-1,2,4-triazol-1-yl)pyridine mol-ecule acts as a terminal ligand. The thio-cyanate ligands function as μ(1,3)-bridging units connecting adjacent Cd(II) atoms with a separation of 5.7525 (11)...

The title compound, [Cd(NCS)(2)(C(6)H(5)N(5))(2)](n), is a coordination polymer with the Cd(II) centre located on a twofold rotation axis. The Cd(II) centre assumes a distorted octa-hedral geometry. The thio-cyanate anions function as bridging ligands between the Cd(II) centres, leading to a chain-like arrangement expanding along [001].
