Descripción
Sumario:Hexa­methyl­phospho­ramide (hmp), tetra­thio­tungstate, 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 anti­prismatic 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.
