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 , 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 .
