Chromium hexafluoride
Chromium hexafluoride or chromium(VI) fluoride 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, but this has been shown to be a misidentification of chromium pentafluoride, CrF5.
CrF6 used to be thought to be produced by exhaustive fluorination of chromium metal at 400 °C (752 °F) and 20 MPa of pressure, and immediate freezing out of the reaction chamber to prevent decomposition:
However, it has been shown that chromium pentafluoride (CrF5) is formed instead:
and that CrF6 has yet to be synthesized.
