Caesium heptafluoroxenate is an inorganic compound of caesium, and fluorine, and xenon with the chemical formula Cs[XeF7]. It consists of caesium cations Cs+ and heptafluoroxenate(VI) cations [XeF7]−.
Preparation
Caesium heptafluoroxenate can be prepared by dissolving caesium fluoride in liquid xenon hexafluoride:[1]
- CsF + XeF6 → Cs[XeF7]
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]
- 2 Cs[XeF7] → Cs2[XeF8] + XeF6
Uses
Caesium heptafluoroxenate is used to isolate xenon hexafluoride from a reaction mixture.
