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

Preparation[edit]

Caesium heptafluoroxenate can be prepared by dissolving xenon hexafluoride in molten caesium fluoride:^[1]

CsF + XeF₆ → CsXeF₇

Properties[edit]

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:^[2]

2CsXeF₇ → Cs₂XeF₈ + XeF₆

Uses[edit]

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