The simplest are mixed-metal oxides of the form MFeO 3, with M=Ba, Ca, or Sr. However, those compounds do not have discrete iron anions. [3] Isolated oxoiron(IV) species are known with more complicated ligands. These compounds model biological complexes such as cytochrome P450, NO synthase, and isopenicillin N synthase. Two such reported ...
The iron compounds produced on the largest scale in industry are iron(II) sulfate (FeSO 4 ·7H 2 O) and iron(III) chloride (FeCl 3). The former is one of the most readily available sources of iron(II), but is less stable to aerial oxidation than Mohr's salt ((NH 4) 2 Fe(SO 4) 2 ·6H 2 O). Iron(II) compounds tend to be oxidized to iron(III ...
Iron shows the characteristic chemical properties of the transition metals, namely the ability to form variable oxidation states differing by steps of one and a very large coordination and organometallic chemistry: indeed, it was the discovery of an iron compound, ferrocene, that revolutionalized the latter field in the 1950s.

Iron(III) stearate (ferric stearate) is a metal-organic compound, a salt of iron and stearic acid with the chemical formula Fe(C 17 H 35 COO)3. [2] [3] The compound is classified as a metallic soap, i.e. a metal derivative of a fatty acid. [4]

Iron(II) perchlorate is the inorganic compound with the formula Fe(ClO 4) 2 ·6H 2 O. A green, water-soluble solid, it is produced by the reaction of iron metal with dilute perchloric acid followed by evaporation of the solution: [3] Fe + 2 HClO 4 + 6 H 2 O → Fe(ClO 4) 2 ·6H 2 O + H 2
Iron(II) chloride tetrahydrate, FeCl 2 ·4H 2 O. In chemistry, iron(II) refers to the element iron in its +2 oxidation state. The adjective ferrous or the prefix ferro-is often used to specify such compounds, as in ferrous chloride for iron(II) chloride (FeCl 2). The adjective ferric is used instead for iron(III) salts, containing the cation Fe 3+.
Iron(III) oxide or ferric oxide is the inorganic compound with the formula Fe 2 O 3. It occurs in nature as the mineral hematite , which serves as the primary source of iron for the steel industry. It is also known as red iron oxide , especially when used in pigments .
