Iron(III) oxide in a vial. 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.
Iron(II,III) oxide, or black iron oxide, is the chemical compound with formula Fe 3 O 4.It occurs in nature as the mineral magnetite.It is one of a number of iron oxides, the others being iron(II) oxide (FeO), which is rare, and iron(III) oxide (Fe 2 O 3) which also occurs naturally as the mineral hematite.
Iron is stored in many organisms in the form of ferritin, which is a ferrous oxide encased in a solubilizing protein sheath. [ 10 ] Species of bacteria , including Shewanella oneidensis , Geobacter sulfurreducens and Geobacter metallireducens , use iron oxides as terminal electron acceptors .
Iron(II) oxide or ferrous oxide is the inorganic compound with the formula FeO. Its mineral form is known as wüstite. [3] [4] One of several iron oxides, it is a black-colored powder that is sometimes confused with rust, the latter of which consists of hydrated iron(III) oxide (ferric oxide).

Ferric iodide, a black solid, is not stable in ordinary conditions, but can be prepared through the reaction of iron pentacarbonyl with iodine and carbon monoxide in the presence of hexane and light at the temperature of −20 °C, with oxygen and water excluded. [13] Complexes of ferric iodide with some soft bases are known to be stable compounds.

Some through all four oxygen atoms, some with two oxygen atoms. Half of the water is lattice water , being situated between chains of Fe oxalates. Mössbauer spectrum of Fe 2 (C 2 O 4 ) 3 · 4 H 2 O exhibits an isomer shift of 0.38 mm/s and a quadrupole splitting of 0.40 mm/s, suggesting a high spin Fe 3+ in octahedral coordination.
