Xenon oxydifluoride

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 and does not form polymers, though it does form an adduct with acetonitrile and with hydrogen fluoride.[1]

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
