title: catena-Poly[[tetra-kis-(hexa-methyl-phospho-ramide-κO)bis-(nitrato-κO,O')yttrium(III)] [silver(I)-di-μ-sulfido-molybdenum(VI)-di-μ-sulfido]].
abstract: In the cation of the title compound, {[Y(NO(3))(2)(C(6)H(18)N(3)OP)(4)][AgMoS(4)]}(n), the Y atom is coordinated by eight O atoms from two chelating nitrate groups and four hexa-methyl-phospho-ramide (hmp) ligands, which gives rise to a distorted square-anti-prismatic environment. Together with the two nitrate ligands, the overall charge for the complex cation is +1, which leads to the anionic chain having a monovalent repeat unit. The polymeric anionic chain, with Mo-Ag-Mo and Ag-Mo-Ag angles of 161.916 (13) and 153.915 (13)°, respectively, presents a distorted linear configuration. The cations and the anions are linked via weak C-H⋯S hydrogen-bonding inter-actions while the cations exhibit inter-molecular C-H⋯O inter-actions. The structure is isotypic with the corresponding W, Yb, Eu, Nd, La and Dy complexes.
