Short description: Unstable artificial chemical compound

Iron(III) sulfide, also known as ferric sulfide or sesquisulfide (Fe₂S₃), is one of the several binary iron sulfides. It is a solid, black powder that degrades at ambient temperature.^[2]

Reactions

Fe₂S₃ precipitates from solutions containing its respective ions:^[2]

2Fe³⁺ + 3S²⁻ → Fe₂S₃

The resulting solid decays at a temperature over 20 °C into iron(II) sulfide (FeS) and elemental sulfur:^[3]

Fe₂S₃ → 2 FeS + S

With hydrochloric acid it decays according to the following reaction equation:^[4]

Fe₂S₃ + 4 HCl → 2 FeCl₂+ 2 H₂S + S

Greigite

Greigite, with the chemical formula Fe2+
Fe3+

2S
4, 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]
