'''六氟化钋'''（PoF<sub>6</sub>）是[[钋]]的一种[[氟化物]]，也是十八种已知的二元[[六氟化物]]之一。它是一种白色不稳定的固体。<ref name=Holleman&Wiberg>{{Holleman&Wiberg|page=594}}</ref>

==制备==
===失败===
曾有化学家试图以如下反应制备它：

:<math>\mathrm{Po + 3\ F_2 \longrightarrow PoF_6}</math>

1945年时进行了这项实验，但没有成功。预测它的沸点为−40&nbsp;°C。<ref>''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] {{Wayback|url=http://www.osti.gov/bridge/product.biblio.jsp?osti_id=443206 |date=20050114164310 }}; [http://www.osti.gov/bridge/servlets/purl/443206-NTUueI/webviewable/443206.pdf PDF].</ref>

===成功===
PoF<sub>6</sub>最终还是由更稳定的钋-208的直接[[氟化]]制得。<ref name="Holleman&Wiberg"/>反应形成了一种挥发性氟化物，<ref>{{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 }}</ref> 但还没有完全表征就分解成[[四氟化钋]]了。<ref>Weinstock, B., Chernick, C.L.: The preparation of a volatile polonium fluoride.
