Iron(III) sulfide, also known as ferric sulfide or sesquisulfide (Fe
2S
3), is one of the several binary
iron sulfides. It is a solid, black powder that degrades at ambient temperature.

3 precipitates from solutions containing its respective ions:
[2]
The resulting solid decays at a temperature over 20 °C into iron(II) sulfide (FeS) and elemental sulfur: [3]
With hydrochloric acid it decays according to the following reaction equation: [4]
Greigite, with the chemical formula Fe2+Fe3+2S4, is a mixed valence compound containing both Fe(III) and Fe(II). It is the sulfur equivalent of the iron oxide magnetite (Fe3O4). As established by X-ray crystallography, the S anions form a cubic close-packed lattice, and the Fe cations occupy both tetrahedral and octahedral sites. [5]
