Uranyl fluoride is the inorganic compound with the formula UO2F2. It is most notable as a contaminant in the production of uranium tetrafluoride.[1]

As shown by X-ray crystallography, the uranyl (UO22+) centers are complemented by six fluoride ligands.[2]

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[3]
