Iron(III) sulfide, also known as ferric sulfide or sesquisulfide (Fe 2 S 3), is one of the several binary iron sulfides. It is a solid, black powder that degrades at ...
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 ... Iron(III) sulfide, Fe 2 S 3; Iron-sulfur clusters, ...
Iron(II) sulfide or ferrous sulfide (Br.E. sulphide) is one of a family of chemical compounds and minerals with the approximate formula Fe S. Iron sulfides are often iron-deficient non-stoichiometric .
Thiocyanate is a common test for the presence of iron(III) as it forms the blood-red [Fe(SCN)(H 2 O) 5] 2+. Like manganese(II), most iron(III) complexes are high-spin, the exceptions being those with ligands that are high in the spectrochemical series such as cyanide. An example of a low-spin iron(III) complex is [Fe(CN) 6] 3−.
The adjective ferric is used instead for iron(III) salts, containing the cation Fe 3+. The word ferrous is derived from the Latin word ferrum , meaning "iron". In ionic compounds (salts), such an atom may occur as a separate cation (positive ion) abbreviated as Fe 2+ , although more precise descriptions include other ligands such as water and ...
In chemistry, iron(III) or ferric refers to the element iron in its +3 oxidation state. Ferric chloride is an alternative name for iron(III) chloride ( FeCl 3 ). The adjective ferrous is used instead for iron(II) salts, containing the cation Fe 2+ .
Iron–sulfur clusters are molecular ensembles of iron and sulfide. They are most often discussed in the context of the biological role for iron–sulfur proteins, which are pervasive. [2] Many Fe–S clusters are known in the area of organometallic chemistry and as precursors to synthetic analogues of the biological clusters.
