The structure of the title Schiff base, C16H17N3O, displays atransconfiguration with respect to the C=N double bond, with a dihedral angle of 14.98 (9)° between the benzene rings. In the crystal, molecules are linked by N—H...O and C—H...O hydrogen-bonding interactions, giving sheets extending across the (001) plane. Hirshfeld surface analysis gave fingerprint plots showing enrichment ratios for H...H, O...H, N...H and C...H contacts compared to C...C, N...N and C...N contacts, indicating a high propensity for H...H interactions to form in the crystal.
