Nitryl azide (tetranitrogen dioxide) is an inorganic compound with the chemical formula N3−NO2. It is an unstable nitrogen oxide consisting of a covalent nitrogen–nitrogen bond between a nitro group and an azide group. It has been detected by infrared spectroscopy as a short-lived product of the reaction between sodium azide and nitronium hexafluoroantimonate:[1]
The compound quickly decomposes to form nitrous oxide. Calculations suggest this process that occurs via an oxatetrazole oxide intermediate:[2]
