Abstract: The complete molecule of title compound, C17H16N4O6, is generated by a crystallographic twofold axis. Within the molecule, the two benzene units are approximately perpendicular, making a dihedral angle of 85.91 (4)°. In the crystal, molecules are linked into a three-dimensional network by C-HO hydrogen bonds and short OO and NO interactions, with distances of 2.998 (2) and 2.968 (3) Å, respectively.
