Abstract
In the crystal structure of the title compound, C(8)H(5)N(3)O(3), inter-molecular N-H⋯O hydrogen bonds link mol-ecules into centrosymmetric dimers. These dimers are, in turn, linked though weak inter-molecular C-H⋯O and C-H⋯N hydrogen bonds and π-π stacking inter-actions, with centroid-centroid distances of 3.678 (3) Å, into a three-dimensional network.Entities:

| Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
