Crystals of the title compound, C13H10N2O, were grown from a dichloro-methane/ketone/methanol solvent mixture. It crystallizes with two molecules, A and B, in the asymmetric unit with very similar almost planar conformations [dihedral angles between the ring planes = 0.74 (8) and 0.67 (6)° for molecules A and B, respectively; r.m.s. overlay fit = 0.019 Å]. Each molecule features an intramolecular N - H⋯N hydrogen bond, which closes an S(6) ring and therefore establishes a syn relationship for the N atoms. In the crystal, molecules are linked by N - H⋯N hydrogen bonds, generating [100] chains containing alternating A and B molecules. Weak aromatic π-π stacking [minimum centroid-centroid separation = 3.6212 (9) Å] links the chains into a three-dimensional network.
