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 caesium fluoride in liquid xenon hexafluoride:

CsF XeF₆ → CsXeF₇

Properties

Caesium heptafluoroxenate is a yellow solid that is stable at room temperature. It is a 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.
