Özet
In the crystal structure of the title compound, C(19)H(18)N(4)O(3), the fused-ring system is essentially planar [maximum deviation is 0.031 ( 2) angstrom] while the dihedral angle between the ring system and the benzene ring is 12.64 (6)degrees. The carbohydrazide H atom is involved in an intramolecular N-H center dot center dot center dot O hydrogen bond, forming a six-membered hydrogen-bonded ring. The molecules arrange themselves into centrosymmetric dimers by means of intermolecular O-H center dot center dot center dot O hydrogen bonds.
