2,2′-(4-{[(E)-4-Methoxybenzylidene]amino}phenylimino)diethanol

Abstract

In the title compound, C18H22N2O3, the dihedral angle between the aromatic rings is 3.9 (2)°. Both H atoms of the hydroxy groups are involved in intermolecular O—H...O hydrogen bonding. In the crystal structure, this hydrogen bonding assembles molecules into chains of 21 symmetry extending parallel to the b axis. The almost planar (within 0.09 and 0.06 Å) 4-CH3O–C6H4–CH=N–C6H4– groups are oriented outwards the twofold screw axis.
