    Iron sulfide or Iron sulphide can refer to range of chemical compounds composed of iron and sulfur. Minerals

  3. Iron(II) sulfide - Wikipedia

    en.wikipedia.org/wiki/Iron(II)_sulfide

    Iron sulfides occur widely in nature in the form of iron–sulfur proteins. As organic matter decays under low-oxygen (or hypoxic ) conditions such as in swamps or dead zones of lakes and oceans, sulfate-reducing bacteria reduce various sulfates present in the water, producing hydrogen sulfide .

  4. Iron–sulfur cluster - Wikipedia

    en.wikipedia.org/wiki/Ironsulfur_cluster

    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.

  5. Iron (II,III) sulfide - Wikipedia

    en.wikipedia.org/wiki/Iron(II,III)_sulfide

    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.

  7. Iron–sulfur protein - Wikipedia

    en.wikipedia.org/wiki/Ironsulfur_protein

    Iron–sulfur proteins are proteins characterized by the presence of iron–sulfur clusters containing sulfide-linked di-, tri-, and tetrairon centers in variable oxidation states. Iron–sulfur clusters are found in a variety of metalloproteins , such as the ferredoxins , as well as NADH dehydrogenase , hydrogenases , coenzyme Q – cytochrome ...
