Xenon dioxydifluoride is an inorganic chemical compound with the formula XeO2F2.[3][2] At room temperature it exists as a metastable solid, which decomposes slowly into xenon difluoride, but the cause of this decomposition is unknown.[2]

Preparation

[edit]

Xenon dioxydifluoride is prepared by reacting xenon trioxide with xenon oxytetrafluoride.[2]

XeO3 + XeOF4 → 2XeO2F2
