Cerium(IV) fluoride explained

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.^[1]

Production and properties

Cerium(IV) fluoride can be produced by fluorinating cerium(III) fluoride or cerium dioxide with fluorine gas at 500 °C^[2]

2 CeF _{3} +F _{2} \longrightarrow2 CeF _{4} CeO _{2} +2 F _{2} \longrightarrowCeF _{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].
