Xenon oxytetrafluoride

Xenon oxytetrafluoride is an inorganic chemical compound. It is an unstable colorless 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 :



A high-yield synthesis proceeds by the reaction of with  at -196 °C.

Like most xenon oxides, it is extremely reactive, and it hydrolyses in water to give hazardous and corrosive products, including hydrogen fluoride:


 * 2 + 4 → 2 + 8 + 3

In addition, some ozone and fluorine is formed.

Reactions
reacts with in the following steps:


 * + →  + 2
 * + →  + 2

The formed is a dangerous explosive, decomposing explosively to Xe and :
 * 2 → 2 + 3

In its liquid form, exhibits amphoteric behaviour, forming complexes with both strong Lewis bases like  and strong Lewis acids like. It forms a 1:1 adduct with, isostructural with ·, as well as various heavy alkali metal fluorides.

The reaction of with  provides a convenient synthesis route for.
