The title compound, C14H12N2O2, is almost planar with an r.m.s. deviation for all non-H atoms of 0.038 Å. The observed planarity is rationalized in terms of a close intramolecular C—H⋯O interaction. Supramolecular layers, two molecules thick and with a step topology, are formed in the crystal packing via C—H⋯O contacts involving the carbonyl O atom, which accepts two such bonds, and π–π interactions between the components of the fused ring system and the phenyl ring of inversion-related molecules [centroid–centroid distances = 3.6819 (13) and 3.6759 (12) Å].
