In the title compound, {[Lu(NO3)2(C6H18N3OP)4][AgWS4]}n, hexa­methyl­phospho­ramide (hmp), tetra­thio­tungstate, silver iodide and lutetium nitrate were self-assembled, forming an anionic {[AgWS4]−}n chain extending parallel to [001]. The LuIII atom in the cation is coordinated by eight O atoms from two nitrate groups and four hmp ligands in a distorted square-anti­prismatic geometry. Together with the two nitrate groups, the cation is monovalent, 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 161.66 (2) and 153.503 (12)°, respectively. The title complex is isotypic with the Y, Yb, Eu, Nd, La, Dy and Sm analogues.
