(E)-3-{4,6-Dimeth-oxy-2-[(E)-4-meth-oxy-styr-yl]-3-methyl-phen-yl}-1-(2-hy-droxy-5-meth-oxy-phen-yl)prop-2-en-1-one.


ABSTRACT: In the title compound, C28H28O6, the benzene rings in the resveratrol moiety are connected by a trans C=C double bond, and the hydroxyl group containing a benzene ring and the central benzene ring are linked through a C=(O)-C=C (enone) moiety to form a chalcone unit. An intra-molecular O-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, pairs of C-H⋯O hydrogen bonds generate dimers and additional weak C-H⋯O inter-actions link the dimers into chains propagating along the b-axis direction.
