Crystal structure of catena-poly[[[bis-(pyridine-4-carbo-thio-amide-κN (1))cadmium]-di-μ-thio-cyanato-κ(2) N:S;κ(2) S:N] methanol disolvate].

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.
