Cerium(IV) fluoride is an inorganic compound with a chemical formula CeF4. It is a strong oxidant that appears as a white crystalline material. Cerium(IV) fluoride has an anhydrous form and a monohydrate form.
Production and properties
Cerium(IV) fluoride can be produced by fluorinating cerium(III) fluoride or cerium dioxide with fluorine gas at 500 °C2
2 C e F 3 + F 2 ⟶ 2 C e F 4 {\displaystyle \mathrm {2\ CeF_{3}+F_{2}\longrightarrow 2\ CeF_{4}} } C e O 2 + 2 F 2 ⟶ C e F 4 + O 2 {\displaystyle \mathrm {CeO_{2}+2\ F_{2}\longrightarrow CeF_{4}+O_{2}} }Its hydrated form (CeF4·xH2O, x≤1) can be produced by reacting 40% hydrofluoric acid and cerium(IV) sulfate solution at 90°C.3
Cerium(IV) fluoride can dissolve in DMSO, and react to form the coordination complex [CeF4(DMSO)2].4
