Interaction of xenon difluoride and xenon tetrafluoride with iodine pentafluoride and the molecular adduct xenon difluoride–iodine pentafluoride

Abstract

Xenon difluoride and xenon tetrafluoride each dissolve in iodine pentafluoride but do not oxidize the solvent at ambient temperatures, even when the fluoride ion acceptor AsF₅ is present. Although XeF₂ forms an adduct XeF₂,IF₅, m.p. 98°,XeF₄ does not. The Raman spectrum of the colourless solid, XeF₂,IF₅, is very nearly a composite of the spectra of XeF₂ and IF₅, suggesting that the compound is essentially molecular.
