Шаблон:Chembox 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]

<math>\mathrm{ 2 \ CeF_3 + F_2 \longrightarrow 2 \ CeF_4 }</math>
<math>\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.[3]

Cerium(IV) fluoride can dissolve in DMSO, and react to form the coordination complex [CeF4(DMSO)2].[3]
