(E)-2-[(2,4,6-Tri­meth­oxy­benzyl­idene)amino]­phenol

There are two independent mol­ecules in the asymmetric unit of the title compound, C(16)H(17)NO(4), with similar conformations but some differences in their bond angles. Each mol­ecule adopts a trans configuration with respect to the methyl­idene C=N bond and is twisted with a dihedral angle between the two substituted benzene rings of 80.52 (7)° in one mol­ecule and 83.53 (7)° in the other. All meth­oxy groups are approximately coplanar with the attached benzene rings, with C(meth­yl)—O—C—C torsion angles ranging from −6.7 (2) to 5.07 (19)°. In the crystal, independent mol­ecules are linked together by O—H⋯N and O—H⋯O hydrogen bonds and a π–π inter­action [centroid–centroid distance of 3.6030 (9) Å], forming a dimer. The dimers are further linked by weak C—H⋯O inter­actions and another π–π inter­action [centroid–centroid distance of 3.9452 (9) Å] into layers lying parallel to the ab plane.
