Abstract: In the molecule of the title Schiff base compound, C₃₀H₂₈N₂O₂, the dihedral angles between the phenol rings and the adjacent dimethylbenzene rings [60.14 (11) and 77.57 (11)°] are distinctly larger than that formed by the dimethylbenzene rings [39.65 (11)°], possibly as a result of the steric hindrance of the methyl groups and the presence of intramolecular O-HN hydrogen bonds.
