title: 4-Methyl-5-(4-nitro-benzyl-idene)-2-oxo-2,5-di-hydro-1H-pyrrole-3-carbo-nitrile.
abstract: Mol-ecules of the potential non-linear optical title compound, C13H9N3O3, form dimeric stacks of mol-ecules along the a axis cross-linked around inversion centers by N-H⋯O hydrogen bonds and weak (phen-yl)C-H⋯O inter-molecular inter-actions, forming a 'collaboration' of R 2 (2)(8) and R 2 (2)(16) ring motifs. The mol-ecules are then further linked by weak C-H⋯O and C-H⋯N inter-actions into sheets parallel to (121).
