Plutonyl fluoride is an inorganic compound of plutonium, oxygen, and fluorine with the chemical formula PuO₂F₂. It was initially isolated by Alenchikova et al. in 1961. ^[1]

Synthesis

Plutonyl fluoride can be obtained by slowly hydrolysing PuF₆. ^{[2] [3]}

PuF₆ (g) + 2 H₂O (g) → PuO₂F₂ (s) + 4 HF (g)

Physical properties

Plutonyl fluoride is soluble in water; the solutions have a pink-to-rose color. ^{[4] [5]}

Chemical properties

In hydrofluoric acid solution, PuO₂F₂ forms a hydrate, PuO₂F₂·H₂O, and a solid incorporating HF, PuO₂F₂·HF·4H₂O. ^[6]
