In the title compound, C17H16N5O, the central tetrazine ring adopts an unsymmetrical boat conformation with the two C atoms as flagpoles. This compound can be considered as having homoaromaticity. The crystal structure is stabilized by intermolecular C—H...O interactions between a benzene H atom and the carbonyl O atom.
