Polonium hexafluoride (PoF
6
) is a possible chemical compound of polonium and fluorine and one of the seventeen known binary hexafluorides.[1]

Synthesis

The synthesis of PoF

via the reaction

210
Po + 3 F

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

208
PoF

was probably successfully synthesised via the same reaction in 1960 with the more stable isotope 208
Po
,[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]
