The molecule of the title compound, C21H16N2O, has crystallographic twofold rotation symmetry, with the C = O group lying on the rotation axis. Intermolecular N-H center dot center dot center dot O hydrogen bonds result in a chain structure containing R-2(1)(6) loops. This orthorhombic structure probably represents a correction of a previous study where space group P2(1) was found.
