The structure determination of the title compound, C8H9N3O3, establishes the N-oxide form of triazene. The overall molecular planarity and trigonal planar geometry of the triazene N atom bonded to the phenyl ring suggest a resonance interaction extending over adjacent atoms. The molecular conformation is stabilized by intramolecular hydrogen bonds and the crystal packing by intermolecular hydrogen bonds.
