Xenon oxytetrafluoride


Xenon oxytetrafluoride is an inorganic chemical compound. It is a colorless stable liquid with a melting point of −46.2°C that can be synthesized by partial hydrolysis of Xenon hexafluoride|, or the reaction of with silica or Sodium nitrate|:
A high-yield synthesis proceeds by the reaction of with Phosphoryl fluoride| at −196 °C.
As are most xenon oxides, it is extremely reactive and unstable, and hydrolyses in water to give dangerously hazardous and corrosive products, including hydrogen fluoride:
In addition, some ozone and fluorine are also formed. This reaction is extremely dangerous, and xenon oxytetrafluoride should therefore be kept away from any trace of water or water vapour under all conditions.

Reactions

XeOF4 reacts with H2O in a following steps:
The XeO3 formed is a dangerous explosive, decomposing explosively to Xe and O2:
In its liquid form, exhibits amphoteric behaviour, forming complexes with both strong Lewis bases like caesium fluoride| and strong Lewis acids like antimony pentafluoride|. It forms a 1:1 adduct with Xenon difluoride|, isostructural with ·, as well as various heavy alkali metal fluorides.
The reaction of with xenon trioxide| provides a convenient synthesis route for xenon dioxide difluoride|.
