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]

XeF₄ + H₂O → XeOF₂ + 2 HF

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 :^[1]

2 XeOF₂ → 2 XeF₂ + O₂

2 XeOF₂ → XeF₂ + XeO₂F₂
