Iron(III) fluoride, also known as ferric fluoride, are inorganic compounds with the formula FeF 3 (H 2 O) x where x = 0 or 3. They are mainly of interest by researchers, unlike the related iron(III) chloride. Anhydrous iron(III) fluoride is white, whereas the hydrated forms are light pink. [2]

Potassium ferrioxalate contains the iron(III) complex [Fe(C 2 O 4) 3] 3−. In chemistry, iron(III) or ferric refers to the element iron in its +3 oxidation state. Ferric chloride is an alternative name for iron(III) chloride (FeCl 3). The adjective ferrous is used instead for iron(II) salts, containing the cation Fe 2+.
Several elements show their highest oxidation state only in a few compounds, one of which is the fluoride; and some elements' highest known oxidation state is seen exclusively in a fluoride. For groups 1–5, 13–16 (except nitrogen), the highest oxidation states of oxides and fluorides are always equal.
As such, the iron cations are octahedral and fluoride anions are trigonal planar. [6] [7] The tetrahydrate can exist in two structures, or polymorphs. One form is rhombohedral and the other is hexagonal, the former having a disorder. [1] Like most fluoride compounds, the anhydrous and hydrated forms of iron(II) fluoride feature high spin metal ...
Fluoride was measured at 8 milligrams per liter in the groundwater of some villages in China, while some Canadian waters contain levels of less than 0.05 milligrams per liter, according to a World ...
