In the title compound, C22H18N4O2, the molecules lie across an inversion centre. The dihedral angle between the mean planes of the central and terminal benzene rings is 66.03 (2)°. The molecule displays trans and anti conformations about the C=N and N—N bonds, respectively. In the crystal, N—HO hydrogen bonds, with the O atoms of C=O groups acting as acceptors, link the molecules into a chain along [101].
