'''五氟化铱'''（化學式：{{化學式|銥|氟|5}}）是一种铱的氟化物，由[[巴特利特]]在1965年最早制得。<ref>{{cite journal |journal=Chem. Commun. |year=1965 |pages=252–253 |doi=10.1039/C19650000252 |title=Iridium pentafluoride |author=Neil Bartlett and P. R. Rao |issue=12}}</ref>它是一种很活泼的低熔点黄色固体，形成四聚体Ir<sub>4</sub>F<sub>20</sub>，其中铱的配位几何为八面体。<ref name = "Wiberg&Holleman">Egon Wiberg, Arnold Frederick Holleman (2001) ''Inorganic Chemistry'', Elsevier ISBN 0-12-352651-5</ref>这种结构与[[五氟化钌|RuF<sub>5</sub>]]和[[五氟化锇|OsF<sub>5</sub>]]类似。

==制备==
五氟化铱可以由[[六氟化铱]]的受控分解<ref name = "Wiberg&Holleman"/>或在无水[[氟化氢]]中用[[硅]]粉或[[氢]]气还原六氟化铱制备。
