Three oxygen compounds of iron are known: ferrous oxide, FeO; ferric oxide, Fe2O3; and ferrosoferric oxide, or ferroferric oxide, Fe3O4, which contains iron in both +2 and +3 oxidation states. Ferrous oxide is a greenish to black powder used primarily as a pigment for glasses.
The iron in hemoglobin is normally maintained in the ferrous state by several effective mechanisms so that only a small percentage of the total hemoglobin is in the form of methemoglobin. The production of methemoglobin by oxidation of the iron to the ferric state, renders the hemoglobin incapable of interacting reversibly with molecular oxygen. The oxygen affinity of the unaffected heme is also increased, resulting in the decreased release of oxygen to the tissues at low partial pressure of oxygen.
