Polonium hexafluoride ({{chem2|PoF6}}) is a possible chemical compound of polonium and fluorine and one of the seventeen known binary hexafluorides.{{Holleman&Wiberg|page=594}}
Synthesis
The synthesis of {{chem2|PoF6}} via the reaction
:{{chem2|^{210}Po + 3 F2 → ^{210}PoF6}}
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; [http://www.osti.gov/bridge/product.biblio.jsp?osti_id=443206 Abstract]; [http://www.osti.gov/bridge/servlets/purl/443206-NTUueI/webviewable/443206.pdf PDF].
{{chem2|^{208}PoF6}} was probably successfully synthesised via the same reaction in 1960 with the more stable isotope {{chem2|^{208}Po}},{{rp|594}} where a volatile polonium fluoride was produced,{{cite journal |last1=Seppelt |first1=Konrad |date=2015 |title=Molecular Hexafluorides |journal=Chemical Reviews |volume=115 |issue=2 |pages=1296–1306 |doi=10.1021/cr5001783|pmid=25418862 }} 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.
