Chromium pentafluoride is the inorganic compound with the chemical formula CrF5. It is a red volatile solid that melts at 30 °C, which easily hydrolyses to chromium(III) and chromium(VI). It has the same crystal structure as vanadium pentafluoride. It is the highest known chromium fluoride, since the hypothetical chromium hexafluoride has not yet been synthesized.
Chromium pentafluoride is one of the products of the action of fluorine on a mixture of potassium and chromic chlorides.
In terms of its structure, the compound is a one-dimensional coordination polymer. Each Cr(V) center has octahedral molecular geometry.〔 "The structures of CrF5 and CrF5
