Xenon oxydifluoride
chemical compound
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.
XeF4 + H2O → XeOF2 + 2 HF
The compound has a T-shaped geometry. 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.
“Xenon oxydifluoride” enters the record as chemical compound. Crown Archives preserves that source wording while asking what Xenon, oxydifluoride and chemical can confirm, complicate or overturn.
Why this record matters
“Xenon oxydifluoride” is worth following because a concise public description often conceals a longer documentary argument. Here, Xenon, oxydifluoride and chemical provides the most credible route into that argument.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jul 27, 2025. The linked authority identifier is Q3359098. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2007.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
