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


The synthesis of PoF6 via the reaction

Po + 3 F

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

PoF6 may have been successfully synthesised via the same reaction in 1960,[1]:594 where a volatile polonium fluoride was produced, but it was not fully characterized.[3]
