【 摘 要 】

The title compound, C28H24N2O3, is a flexible Schiff base, having a dihedral angle of 59.53 (5)° between the mean planes of two phenyl rings bounded in the centre by a single O atom. The dihedral angles between the mean planes of the phenyl rings bonded to the central O atom and the mean planes of the terminal methyl­phenol rings are 31.47 (6) and 36.03 (5)°, respectively. The sp2-hybridized character of the azanylylidene groups is confirmed by their bond lengths and bond angles. In the crystal, mol­ecules are linked into centrosymmetric dimers by weak C—H⋯N inter­actions and connected into dimeric chains through weak C—H⋯O inter­actions. These chains are inter­connected into a two-dimensional network parallel to (1\overline{2}1) via weak C—H⋯π inter­actions.
