Reaction of elemental antimony with sulfur under mild hydrothermal conditions yielded different polysulfido‐clusters of antimony. These were isolated as tetraphenylphosphonium salts [P(C 6 H 5 ) 4 ] 3 Sb 3 S 25 and [P(C 6 H 5 ) 4 ] 2 Sb 2 S 15 · 2(C 3 N 2 H 6 ) and their crystal structures were determined. In the first compound two different polysulfide anions are observed, Sb 2 S 17 2– and Sb 2 S 16 2– , whereas the second contains the Sb 2 S 15 2– complex. These dinuclear anions show as a common building principle two ψ‐trigonal bipyramidal coordinated Sb centers bridged by two S x 2– units and an additional S x 2– chelate ligand bound to each Sb center giving a tricyclic structure.
