Catena-Poly[2-methyl-pyridinium [tungstate-di-?-selenido-silver-di-?-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.

Project description:Hexa-methyl-phospho-ramide (hmp), tetra-thio-tungstate, silver sulfide and cerium nitrate were self-assembled to form a one-dimensional anionic [Ag(4)W(4)S(16)](n) (4n-) chain in the title compound, {[Ce(NO(3))(2)(C(6)H(18)N(3)OP)(4)][AgWS(4)]}(n). The asymmetric unit contains four crystallographically independent [Ce(hmp)(4)(NO(3))(2)](+) cations, which leads to a one-dimensional polymeric anionic chain having a tetra-valent [W(4)S(16)Ag(4)] repeat unit. Each central Ce atom is coordinated by eight O atoms from two chelating nitrate and four hmp ligands, which gives rise to a distorted square-anti-prismatic structure. The polymeric chain with average W-Ag-W and Ag-W-Ag bond angles of 163.75 and 151.84°, respectively, presents a distorted linear configuration. The title complex with a non-centrosymmetric structure, is analogous to the Yb, Y, Eu, Nd, La and Dy isomorphs, which exhibit centrosymmetric structures.
