Iron(II,III) sulfide is a blue-black (sometimes pinkish [citation needed]) chemical compound of iron and sulfur with formula Fe 3 S 4 or FeS·Fe 2 S 3, which is much similar to iron(II,III) oxide. It occurs naturally as the sulfide mineral greigite and is magnetic. It is a bio-mineral produced by and found in magnetotactic bacteria.
Iron sulfide or Iron sulphide can refer to range of chemical compounds composed of iron and sulfur. Minerals. By increasing order of stability: Iron(II) sulfide ...
Molybdenum disulfide (MoS 2) consists of separated sulfide centers, in association with molybdenum in the formal +4 oxidation state (that is, Mo 4+ and two S 2−). Iron disulfide (pyrite, FeS 2) on the other hand consists of S 2− 2, or − S–S − dianion, in association with divalent iron in the formal +2 oxidation state (ferrous ion: Fe 2+).
The mineral pyrite (/ ˈ p aɪ r aɪ t / PY-ryte), [6] or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula Fe S 2 (iron (II) disulfide). Pyrite is the most abundant sulfide mineral .
All the iron(II) sulfates dissolve in water to give the same aquo complex [Fe(H 2 O) 6] 2+, which has octahedral molecular geometry and is paramagnetic. The name copperas dates from times when the copper(II) sulfate was known as blue copperas, and perhaps in analogy, iron(II) and zinc sulfate were known respectively as green and white copperas ...
