Chemical compound
Uranyl fluoride is the inorganic compound with the formula UO2F2. As shown by x-ray crystallography, the uranyl (UO22+) centers are complemented by six fluoride ligands.[1]
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[2]
