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)
