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]
