1315-04-4[S].[Sb]YPMOSINXXHVZIL-UHFFFAOYSA-N1315-04-4、1317-86-8Antimony pentasulfide is an orange to dark red powder. It is doubtful whether stoichiometric Sb2S5 exists, because the preparations contain free sulfur and have variable composition. Antimony pentasulfide is insoluble in water but soluble in alkalies and alkali-metal carbonates.

The compound is made commercially by converting antimony trisulfide to tetrathioantimonate by boiling with sulfur in caustic soda solution:4 Sb2S3 + 8 S +18 NaOH → 5 Na3SbS4 + 3 NaSbO3 + 9 H2OThe sparingly soluble sodium antimonate is filtered out of the solution. The yellow-orange antimony pentasulfide precipitates out on treatment with hydrochloric acid.2 Na3SbS4 + 6 HCl → Sb2S5 + 6 NaCl + 3 H2SIt may also be prepared by the reaction of antimony pentachloride in HCl with hydrogen sulfide and removing any free sulfur by extraction with carbon disulfide:2 SbCl5 + 5 H2S → Sb2S5 + 10 HCl.
