Cerium(IV) fluoride

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 °C

${\displaystyle \mathrm {2\ CeF_{3} F_{2}\longrightarrow 2\ CeF_{4}} }$

${\displaystyle \mathrm {CeO_{2} 2\ F_{2}\longrightarrow CeF_{4} O_{2}} }$

Its hydrated form (CeF₄·xH₂O, x≤1) can be produced by reacting 40% hydrofluoric acid and cerium(IV) sulfate solution at 90°C.

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