Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).

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 a 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.
