چکیده
In the asymmetric unit of the title compound, C(14)H(11)N(5)O(6), there are three crystallographically independent mol-ecules with similar conformations but some differences in bond angles. The mol-ecules are slightly twisted with the dihedral angles between the benzene rings being 10.02 (14), 8.41 (15) and 1.40 (14)°. In each mol-ecule, an intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked by weak C-H⋯O inter-actions into a three-dimensional network. π-π inter-actions with centroid-centroid distances of 3.5635 (17)-3.8273 (18) Å are observed.
