Catena-Poly[[tetra-kis-(hexa-methyl-phospho-ramide-?O)bis-(nitrato-?O,O')dysprosium(III)] [silver(I)-di-?-sulfido-tungstate(VI)-di-?-sulfido]].


ABSTRACT: Hexa-methyl-phospho-ramide (hmp), tetra-thio-tungstate, silver sulfide and dysprosium nitrate were self-assembled, forming an anionic [AgWS(4)](n) (n) (-) chain in the title compound, {[Dy(NO(3))(2)(C(6)H(18)N(3)OP)(4)][AgWS(4)]}(n). The central Dy atom in the cation is coordinated by eight O atoms from two didentate nitrate and four hmp ligands, giving rise to a distorted square anti-prismatic structure. Together with the two nitrate ligands, the cation is univalent, which leads to the anionic chain having a [WS(4)Ag] repeat unit. The polymeric anionic chain, with W-Ag-W and Ag-W-Ag angles 161.16?(2) and 153.606?(11)°, respectively, presents a distorted linear configuration. The title compound is isotypic with other rare earth complexes.
