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.[2]
Production and properties
Cerium(IV) fluoride can be produced by fluorinating cerium(III) fluoride or cerium dioxide with fluorine gas at 500 °C[3]
- [math]\displaystyle{ \mathrm{ 2 \ CeF_3 + F_2 \longrightarrow 2 \ CeF_4 } }[/math]
- [math]\displaystyle{ \mathrm{ CeO_2 + 2 \ F_2 \longrightarrow CeF_4 + O_2 } }[/math]
Its hydrated form (CeF4·xH2O, x≤1) can be produced by reacting 40% hydrofluoric acid and cerium(IV) sulfate solution at 90°C.[4]
Cerium(IV) fluoride can dissolve in DMSO, and react to form the coordination complex [CeF4(DMSO)2].[4]
