Iron(II) fluoride has formula FeF₂ and can be encountered as the anhydrous form or as the tetrahydrate, FeF₂.4H₂O, (CAS Number 13940-89-1). The anhydrous salt can be made from the elements.Greenwood&Earnshaw] FeF₂ has the TiO₂ rutile structure where the iron atoms are octahedrally coordinated and the fluoride ions three coordinate.. FeF₂ is soluble in water from which the tetrahydrate can be formed.
