Xenon oxydifluoride
Chemical compound
From Wikipedia, the free encyclopedia
Xenon oxydifluoride is an inorganic compound with the molecular formula XeOF2. The first definitive isolation of the compound was published on 3 March 2007, producing it by the previously-examined route of partial hydrolysis of xenon tetrafluoride.[1]

The compound has a T-shaped geometry.[1] It is a weak Lewis acid, adducing acetonitrile and forming the trifluoroxenate(IV) ion in hydrogen fluoride. With strong fluoride acceptors, the latter generates the hydroxydifluoroxenonium(IV) ion (HOXeF+
2), suggesting a certain Brønsted basicity as well.[2]
Although stable at low temperatures, it rapidly decomposes upon warming, either by losing the oxygen atom or by disproportionating into xenon difluoride and xenon dioxydifluoride:[1]
- 2 XeOF2 → 2 XeF2 + O2
- 2 XeOF2 → XeF2 + XeO2F2
