Abstract: In the asymmetric unit of the title compound, C14H11N5O6, there are three crystallographically independent mol­ecules with similar conformations but some differences in bond angles. The mol­ecules are slightly twisted with the dihedral angles between the benzene rings being 10.02 (14), 8.41 (15) and 1.40 (14)°. In each mol­ecule, an intra­molecular N-H...O hydrogen bond generates an S(6) ring motif. In the crystal, mol­ecules are linked by weak C-H...O inter­actions into a three-dimensional network. [pi]-[pi] inter­actions with centroid-centroid distances of 3.5635 (17)-3.8273 (18) Å are observed.
