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
