Characteristic
Iron(III) fluoride, also known as ferric fluoride, are inorganic compounds with the formula FeF3(H2O)x where x = 0 or 3. Anhydrous iron(III) fluoride is white, whereas the hydrated forms are light pink.
Chemical formula：FeF3
Molar mass：112.840 g/mol (anhydrous)
166.89 g/mol (trihydrate)
Appearance：pale green crystals
Density：3.87 g/cm3 (anhydrous)
2.3 g/cm3 (trihydrate)
Melting point：> 1,000 °C (1,830 °F; 1,270 K)
Solubility in water：slightly soluble (anhydrous)
49.5 g/100 mL (trihydrate)
Solubility：negligible in alcohol, ether, benzene
Magnetic susceptibility (χ)：+13,760·10−6 cm3/mol
Crystal structure：Rhombohedral, hR24
Application
The primary commercial use of iron(III) fluoride in the production of ceramics.
Some cross coupling reaction are catalyzed by ferric fluoride-based compounds. Specifically the coupling of biaryl compounds are catalyzed by hydrated iron(II) fluoride complexes of N-heterocyclic carbene ligands. Other metal fluorides also catalyse similar reactions. Iron(III) fluoride has also been shown to catalyze chemoselective addition of cyanide to aldehydes to give the cyanohydrins.
