Krypton fluoride chemistry; a route to AuF5, KrF+AuF6–, Xe2F3+AuF6–, and NO+AuF6–: the KrF+–XeOF4 system

Abstract

Pyrolysis of newly prepared KrF⁺AuF₆^– gives AuF₅ which reacts with XeF₂ to produce Xe₂F₃⁺AuF₆^– and NOF to give NO⁺AuF₆^–; Kr⁺AuF₆^– is a powerful oxidative fluorinating agent with respect to O₂ and Xe and the reaction of KrF⁺ with excess XeOF₄ gives XeOF₄.XeF₅⁺ and O₂⁺ salts, not XeOF₅⁺ as reported previously.
