Nitrosonium octafluoroxenate(VI) is a chemical compound of xenon with nitrogen, oxygen, and fluorine, having formula (NO)
₂XeF
₈. It is an ionic compound containing well-separated nitrosonium cations (NO⁺) and octafluoroxenate(VI) anions (XeF²⁻
₈). The molecular geometry of the octafluoroxenate(VI) ion is square antiprismatic, having Xe–F bond lengths of 1.971 Å, 1.946 Å, 1.958 Å, 2.052 Å, and 2.099 Å.^[1]

It is synthesized by the reaction of xenon hexafluoride (XeF
₆) with nitrosyl fluoride (NOF):^[2]

XeF
₆ + 2 NOF → (NO)
₂XeF
₈

Other compounds containing the octafluoroxenate(VI) ion include its alkali metal salts, including Cs₂XeF₈ and Rb₂XeF₈, which are stable up to 400 °C.^[3]^[4]
