Chemical compound
Iron oxychloride is the inorganic compound with the formula FeOCl. This purple solid adopts a layered structure, akin to that of cadmium chloride.[1] The material slowly hydrolyses in moist air. The solid intercalates electron donors such as tetrathiafulvalene and even pyridine to give mixed valence charge-transfer salts. Intercalation is accompanied by a marked increase in electrical conductivity and a color change to black.[2]
Production
FeOCl is prepared by heating iron(III) oxide with ferric chloride at 370 °C (698 °F) over the course of several days:[2]
- Fe2O3 + FeCl3 → 3 FeOCl
Alternatively, FeOCl may be prepared by the thermal decomposition of FeCl3⋅6H2O at 220 °C (428 °F) over the course of one hour:[3]
- FeCl3 ⋅ 6H2O → FeOCl + 5 H2O + 2 HCl
