Descripción
Sumario:In the title salt, {[Ho(NO(3))(2)(C(6)H(18)N(3)OP)(4)][AgWS(4)]}(n), the anion forms a W/S/Ag polymeric chain along the a axis. The holmium atom in the cation is coordinated by eight O atoms from two nitrate and four hexa­methyl­phospho­ramide ligands in a distorted square-anti­prismatic geometry. Together with the two nitrate ligands, the complex cation in the title compound is univalent, which leads the anion to be univalent as well. The polymeric anionic chain with W—Ag—W and Ag—W—Ag angles of 161.429 (17) and 153.608 (10) °, respectively, presents a distorted linear configuration. The title complex is isotypic with the corresponding Y, Yb, Eu, Nd, La and Dy analogues.
