Polonium hexafluoride (PoF₆) is a possible chemical compound of polonium and fluorine and one of the seventeen known binary hexafluorides.

Synthesis

The synthesis of PoF₆ via the reaction

Po + 3 F₂ → PoF₆

was attempted in 1945, but the attempt was unsuccessful. The boiling point was predicted to be about −40 °C.

PoF₆ was probably successfully synthesised via the same reaction in 1960 with the more stable isotope Po, where a volatile polonium fluoride was produced, but it was not fully characterized before it underwent radiolysis and decomposed to polonium tetrafluoride.
