چکیده
In the title compound, C(8)H(6)N(2)O(6), the O atoms of the nitro groups, the methyl H atoms and the carboxyl C=O and C-OH groups are disordered over two sets of sites with an occupancy ratio of 0.595 (16):0.405 (16). In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds arise for both carboxyl disorder components and C-H⋯O bonds and weak C-H⋯π inter-actions consolidate the packing.

The asymmetric unit of the title co-crystal, C(7)H(6)N(2)·C(7)H(4)N(2)O(6), contains two formula units of both components. The crystal structure is stabilized by inter-molecular O-H⋯O, N-H⋯O, N-H⋯N and C-H⋯O hydrogen bonds, generating a two-dimensional wave-like network. π-π stacking inter-actions [centroid-centroid distances = 3.702 (2), 3.660 (2)and 3.671 (2) Å] stabilize the crystal packing.
