Crystal structure of catena-poly[bis­­(pyridine-4-carbo­thio­amide-κN1)cadmium]-di-μ-thio­cyanato-κ2N:S;κ2S: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 thio­cyanate anion, one pyridine-4-carbo­thio­amide ligand and one methanol mol­ecule in general positions. The CdII cations are octa­hedrally coordinated by the pyridine N atom of two pyridine-4-carbo­thio­amide ligands and by the S and N atoms of four thio­cyanate anions and are linked into chains along [010] by pairs of anionic ligands. These chains are further linked into layers extending along (201) by inter­molecular N—H⋯O and O—H⋯S hydrogen bonds. One of the amino H atoms of the pyridine-4-carbo­thio­amide ligand is hydrogen-bonded to the O atom of a methanol mol­ecule, and a symmetry-related methanol mol­ecule is the donor group to the S atom of another pyridine-4-carbo­thio­amide ligand whereby each of the pyridine-4-carbo­thio­amide ligands forms two pairs of centrosymmetric N—H⋯S and O—H⋯S hydrogen bonds. The methanol mol­ecules are equally disordered over two orientations.
