Chemical compound

Polonium hexafluoride (PoF₆) is a possible chemical compound of polonium and fluorine and one of the seventeen known binary hexafluorides.^[1]

Synthesis

The synthesis of PoF₆ via the reaction

²¹⁰Po + 3 F₂ → ²¹⁰PoF₆

was attempted in 1945, but the attempt was unsuccessful. The boiling point was predicted to be about −40 °C.^[2]

²⁰⁸PoF₆ was probably successfully synthesised via the same reaction in 1960 with the more stable isotope ²⁰⁸Po,^[1]^: 594 where a volatile polonium fluoride was produced,^[3] but it was not fully characterized before it underwent radiolysis and decomposed to polonium tetrafluoride.^[4]^[5]
