Abstract

In the title compound, {[Tb(NO3)2(C6H18N3OP)4][AgWS4]}n, the polymeric anionic chain {[AgWS4]−}n extends along [001]. The TbIII atom in the cation is coordinated by eight O atoms from two nitrate and four hexamethylphosphate ligands in a distorted square-anti­prismatic geometry. 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 has a distorted linear configuration with W—Ag—W and Ag—W—Ag angles of 161.49 (2) and 153.743 (13) °, respectively. The title complex is isotypic with the Y, Yb, Eu, Nd, La, Dy, Sm and Lu analogues.
