Catena-Poly[2-methyl-pyridinium [tungstate-di-μ-selenido-silver-di-μ-selenido] 2-methyl-pyridine monosolvate].

ABSTRACT: The title compound, {(C6H8N)[AgWSe4]·C6H7N} n , consists of anionic [WAgSe4] n chains, 2-methyl-pyridinium cations and neutral 2-methyl-pyridine mol-ecules. The Se atoms bridge the Ag and W atoms, forming a polymeric chain extending along the b-axis direction. Both the Ag and W atoms are located on a twofold rotation axis and each metal atom is coordinated by four Se atoms in distorted tetra-hedral geometry. In the crystal, the 2-methyl-pyridinium cation and 2-methyl-pyridine mol-ecule are linked via N-H⋯N hydrogen bonding. Weak C-H⋯Se inter-actions link the organic components and polymeric anions into a three-dimensional architecture.
