Crystal structure of (E)-2,6-dimethoxy-4-{[(4-methoxyphenyl)imino]methyl}phenol

Abstract

In the title compound, C16H17NO4, the dihedral angle between benzene rings is 72.7 (2)°. The methoxy groups are rotated by 2.4 (2) and −4.9 (2) (benzilidene moiety) and by 5.6 (3)° (aniline moiety) relative to the adjacent benzene ring. In the crystal, the molecules are linked into chains along [101] through C—H...O and O—H...N hydrogen bonds.
