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

Synthesis[edit]

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

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