Crystal structure of (E)-2-hy­droxy-4′-meth­oxy­aza­stilbene

The title aza­stilbene derivative, C(14)H(13)NO(2) {systematic name: (E)-2-[(4-meth­oxy­benzyl­idene)amino]­phenol}, is a product of the condensation reaction between 4-meth­oxy­benzaldehyde and 2-amino­phenol. The mol­ecule adopts an E conformation with respect to the azomethine C=N bond and is almost planar, the dihedral angle between the two substituted benzene rings being 3.29 (4)°. The meth­oxy group is coplanar with the benzene ring to which it is attached, the C(meth­yl)—O—C—C torsion angle being −1.14 (12)°. There is an intra­molecular O—H⋯N hydrogen bond generating an S(5) ring motif. In the crystal, mol­ecules are linked via C—H⋯O hydrogen bonds, forming zigzag chains along [10-1]. The chains are linked via C—H⋯π inter­actions, forming a three-dimensional structure.
