Xenon oxydifluoride is an inorganic compound with the molecular formula XeOF 2.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.
Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.
4 exhibits amphoteric behaviour, forming complexes with both strong Lewis bases like CsF and strong Lewis acids like SbF 5. [7] It forms a 1:1 adduct with XeF 2, isostructural with XeF 2 · IF 5, [8] as well as various heavy alkali metal fluorides. [4] The reaction of XeOF 4 with XeO 3 provides a convenient synthesis route for XeO 2 F 2. [9]
One example is xenon hydrate (Xe· 5 + 3 ⁄ 4 H 2 O), where xenon atoms occupy vacancies in a lattice of water molecules. [32] This clathrate has a melting point of 24 °C. [33] The deuterated version of this hydrate has also been produced. [34] Another example is xenon hydride (Xe(H 2) 8), in which xenon pairs are trapped inside solid ...

The cationic metal centres act as Lewis acid sites while the anionic oxygen centres act as Lewis bases. Surface hydroxyl groups can serve as Brønsted acid or base sites as they can give up or accept a proton. [14] The surface of most metal oxides will be, to some extent, hydroxylated under normal conditions when water vapor is present. [15]
XeO 2 is a yellow-orange solid. [4] It is an unstable compound, with a half-life of about two minutes, disproportionating into XeO 3 and xenon gas. Its structure and identity was confirmed by cooling it to −150 °C so that Raman spectroscopy could be performed before it decomposed.
In the crystal structure of this product the magnesium atom is octahedrally-coordinated and the XeF 2 ligands are axial while the AsF − 6 ligands are equatorial. Many such reactions with products of the form [M x (XeF 2 ) n ](AF 6 ) x have been observed, where M can be calcium , strontium , barium , lead , silver , lanthanum , or neodymium ...
