Cerium(IV) fluoride is an inorganic compound with a chemical formula CeF<sub>4</sub>. It is a strong oxidant that appears as a white crystalline material. Cerium(IV) fluoride has an anhydrous form and a monohydrate form.
Cerium(IV) fluoride can be produced by fluorinating cerium(III) fluoride or cerium dioxide with fluorine gas at 500 ðC
Its hydrated form (CeF<sub>4</sub>÷xH<sub>2</sub>O, xâ¤1) can be produced by reacting 40% hydrofluoric acid and cerium(IV) sulfate solution at 90ðC.
Cerium(IV) fluoride can dissolve in DMSO, and react to form the coordination complex [CeF<sub>4</sub>(DMSO)<sub>2</sub>].
