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

Contents

Preparation

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

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: [2]

2CsXeF7 → Cs2XeF8 + XeF6

Uses

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