Ferric Fluoride

Ferric Fluoride (Iron(III) fluoride), with the chemical formula FeF3, is an inorganic compound appearing as a white to pale green crystalline solid. It is thermally stable with a high melting point of about 1000°C and has a density of approximately 3.87 g/cm³. Ferric fluoride is insoluble in alcohol, ether, and benzene, and slightly soluble in water and dilute hydrofluoric acid.

Ferric fluoride exhibits a rhombohedral crystal structure with octahedral coordination around the iron(III) centers. It is used primarily in materials science for fluoride-based ceramics and glasses, as well as a catalyst in certain organic synthesis reactions and cross-coupling processes. Due to its corrosive nature and fluoride content, it requires careful handling and storage in a cool, dry, and well-ventilated area.
