Chromium pentafluoride is a compound of chromium and fluorine. Its chemical formula is CrF
5
.[2] It is a red volatile solid that melts at 30 °C, which easily hydrolyses to chromium(III) and chromium(VI).[3] It has the same crystal structure as vanadium pentafluoride.[4] It is the highest known chromium fluoride, since the hypothetical chromium hexafluoride has not yet been synthesized.[5]

Chromium pentafluoride is one of the products of the action of fluorine on a mixture of potassium and chromic chlorides.[6]
