A one‐dimensional polymeric anion chain , composed of octanuclear cyclic cluster fragments [W 4 Ag 4 S 16 ] 4− linked through Ag + ions (see below), has been isolated from the ammonium tetrathiotungstate/silver nitrate system. Lanthanide( III ) ions (Nd or La), which are coordinated by eight DMF ligands and play a crucial role in the formation of the cluster compound, are encapsulated between the chains.
