Polonium hexafluoride () is a possible chemical compound of polonium and fluorine and one of the seventeen known binary hexafluorides.
Synthesis The synthesis of via the reaction
was attempted in 1945, but the attempt was unsuccessful. The boiling point was predicted to be about −40 °C.Summary of work to date on volatile neutron source, Monsanto Chemical Company, Unit 3 abstracts of progress reports, August 16–31, 1945; Abstract; PDF.
was probably successfully synthesised via the same reaction in 1960 with the more stable isotope , where a volatile polonium fluoride was produced, but it was not fully characterized before it underwent radiolysis and decomposed to polonium tetrafluoride.Weinstock, B., Chernick, C.L.: The preparation of a volatile polonium fluoride.
