Chromium hexafluoride

Chromium hexafluoride or chromium(VI) fluoride (CrF₆) is a hypothetical chemical compound between chromium and fluorine with the chemical formula CrF₆. It was previously thought to be an unstable yellow solid decomposing at −100 °C,^[1] but this has been shown to be a misidentification of chromium pentafluoride, CrF₅.^[2]
