Abstract
Hexamethylphosphoramide (hmp), tetrathiotungstate, silver sulfide and dysprosium nitrate were self-assembled, forming an anionic [AgWS4]nn − chain in the title compound, {[Dy(NO3)2(C6H18N3OP)4][AgWS4]}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 [WS4Ag] 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.
