Abstract: In the title compound, C16H16N4O6, the planes of the isoindole and dinitrobenzene groups make a dihedral angle between of 84.15 (8)°. The N atom of the isoindole group is displaced by 0.2937 (3) Å from the plane through the remaining atoms. An intramolecular N-HO interaction occurs. In the crystal, inversion dimers linked by pairs of N-HO hydrogen bonds occur.
