Abstract: In the crystal structure, the title Schiff base compound, C₂₃H₃₀N₂O₄, exhibits crystallographic twofold rotation symmetry. The imino group is coplanar with the aromatic ring with an N-C-C-C torsion angle of -179.72 (9)°. An intramolecular O-HN hydrogen bond forms a six-membered ring, producing an S(6) ring motif. The dihedral angle between symmetry related benzene rings is 28.05 (5)°. The ethoxy group makes a C-O-C-C torsion angle of -7.20 (16)° with the benzene ring. The crystal structure is stabilized by intermolecular C-H interactions.
