Caesium heptafluoroxenate

Caesium heptafluoroxenate is an inorganic compound of caesium, and fluorine, and xenon with the chemical formula CsXeF7.

Preparation
Caesium heptafluoroxenate can be prepared by dissolving xenon hexafluoride in molten caesium fluoride:
 * CsF + XeF6 -> CsXeF7

Properties
Caesium heptafluoroxenate is a yellow solid that is stable at room temperature. It is very strong oxidizer. The compound decomposes at 50 °C to produce caesium octofluoroxenate:


 * 2CsXeF7 -> Cs2XeF8 + XeF6

Uses
Caesium heptafluoroxenate is used to isolate xenon hexafluoride from a reaction mixture.
