Abstract: Molecules of the potential non-linear optical title compound, C13H9N3O3, form dimeric stacks of molecules along the a axis cross-linked around inversion centers by N-H...O hydrogen bonds and weak (phenyl)C-H...O intermolecular interactions, forming a `collaboration' of R22(8) and R22(16) ring motifs. The molecules are then further linked by weak C-H...O and C-H...N interactions into sheets parallel to (121).
