Crystal structure of (E)-4,6-dimethoxy-2-(4-methoxystyryl)-3-methylbenzaldehyde

Abstract

In the title molecule, C19H20O4, the central C=C double bond adopts an E configuration. The dihedral angle formed by the planes of the two benzene rings is 83.57 (12)°. The three methoxy groups are essentially coplanar with the benzene rings to which they are attached, with C...;C—O—C torsion angles of −0.2 (3), −2.3 (3) and −4.1 (3)°.
