Abstract
In the title compound, C17H16N4O4, the dihedral angle between the planar nine-membered bicyclic ring system and the benzene ring is 81.9 (1)degrees. Intramolecular N-H center dot center dot center dot O and intermolecular N-H center dot center dot center dot O, N-H center dot center dot center dot N and C-H center dot center dot center dot N hydrogen bonds are effective in stabilizing the molecular and crystal structure.
