Chemical compound

Uranyl fluoride is the inorganic compound with the formula UO2F2. It is most notable as a contaminant in the production of uranium tetrafluoride.

As shown by X-ray crystallography, the uranyl (UO2) centers are complemented by six fluoride ligands.

This salt is very soluble in water as well as hygroscopic. It is formed in the hydrolysis of uranium hexafluoride (UF6):

UF6 + 2 H2O → UO2F2 + 4 HF

It can also be formed in the hydrofluorination of uranium trioxide (UO3):

UO3 + 2 HF → UO2F2 + H2O
