Template:Chembox new Iron(III) fluoride is a chemical with the formula FeF3. It can be encountered as the anhydrous form or as the pink trihydrate. The anhydrous form contains octahedral FeF6 units that share vertices.[1] When heated under vacuum it decomposes to give FeF2 and F2.[1] In the gas phase at 1260°K the structure is planar D3h with an Fe-F bond length of 176.3pm.[2]
The formation of ferric fluoride may have been responsible for a fluorine gas cylinder explosion at a University of California lab. [3]
