Quick Summary

Krypton difluoride (KrF₂) is a chemical compound formed by the reaction of krypton and fluorine. It is a colorless, crystalline solid that is highly volatile and decomposes at room temperature. KrF₂ is a powerful oxidative fluorinating agent, meaning it can transfer fluorine atoms to other substances while also removing electrons.1

This compound can react with other elements, such as xenon, to form new compounds like xenon hexafluoride (XeF₆). KrF₂ can also form complex salts with strong fluoride-ion acceptors, creating cations like KrF⁺ and Kr₂F₃⁺. These cations are among the most powerful chemical oxidizers known.1
