Uranyl fluoride is the inorganic compound with the formula UO

2. It is most notable as a contaminant in the production of uranium tetrafluoride.[3]

As shown by X-ray crystallography, the uranyl centers UO2+
2 are surrounded by six fluoride ligands F−
.[4]

## Synthesis

It is formed in the hydrolysis of uranium hexafluoride (UF
6):

6 \+ 2 H
2O → UO

2 \+ 4 HF

It can also be formed in the hydrofluorination of uranium trioxide (UO
3):

3 \+ 2 HF → UO

2 \+ H
2O[5]
