Fe2Cl3

Fe2Cl3 is not a recognized chemical compound. The common iron chlorides are iron(II) chloride, with the formula FeCl2, and iron(III) chloride, with the formula FeCl3. Iron(II) chloride is a pale green solid and is paramagnetic. It is soluble in water and is often used as a reducing agent and in the production of iron pigments. Iron(III) chloride is a crystalline solid with the formula FeCl3. It is typically dark brown or yellow and is strongly acidic and corrosive. It is highly soluble in water and is used in water treatment, as a catalyst in organic reactions, and in etching printed circuit boards. The valency of iron in these compounds is +2 and +3 respectively. If there was a compound with the formula Fe2Cl3, it would imply an average iron oxidation state of +1.5, which is not a stable or commonly observed oxidation state for iron in simple ionic compounds. Therefore, Fe2Cl3 is likely a typo or a misunderstanding of existing iron chloride compounds.
