Uranyl fluoride is the inorganic compound with the formula UO
2F
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):
- UF
6 + 2 H
2O → UO
2F
2 + 4 HF
It can also be formed in the hydrofluorination of uranium trioxide (UO
3):
- UO
3 + 2 HF → UO
2F
2 + H
2O[5]
