catena-Poly[[bis(nicotinamide-kappa N1)copper(I)]-mu-thiocyanato-kappa 2N:S]

The Cu(I) cations in the title compound, [Cu(NCS)(C(6)H(6)N(2)O)(2)](n), are coordinated by N atoms from each of two mirror-related nicotinamide ligands, as well as by one N atom of one thiocyanate ligand and one S atom of a symmetry-related thiocyanate ligand, within a slightly distorted tetrahedron. The Cu(I) cations and the thiocyanate anions are located on a crystallographic mirror plane and the nicotinamide ligands occupy general positions. The Cu(I) cations are connected by the thiocyanate anions to form chains in the direction of the crystallographic a axis. These chains are connected by hydrogen bonds between the amide H atoms and the O atoms of adjacent nicotinamide ligands, to give a three-dimensional structure.
