Chromium oxytetrafluoride is the inorganic compound with the formula CrOF
4. It is a purple, volatile, diamagnetic solid. The compound is classified as an oxyfluoride.[1][2]
Synthesis
It can be prepared by fluorination of chromyl fluoride with krypton difluoride:[3]
- 2 CrO
2F
2 + 2 KrF
2 → 2 CrOF
4 + O
2 + 2 Kr
The compound serves as a weak Lewis base with noble gas difluorides.[4] It also binds fluoride to give the pentafluoride.
