Reaction of elemental antimony with sulfur under mild hydrothermal conditions yielded different polysulfidoclusters 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 determi
The structure of the compound was deduced from the 119Sn and 31P NMR spectra 3 and it was shown to be a structural analogue of the hetero-nortricyclene The apical phosphorus atom P 4 S 3 . exhibits an extremely negative 31P chemical shift of [554.65 ppm, and the basal phosphorus atoms also resonat
