(E)-3-(3,5-Dimethoxyphenyl)-1-(1-hydroxynaphthalen-2-yl)prop-2-en-1-one

Abstract

In the title molecule, C21H18O4, the C=C bond of the central enone group adopts a trans conformation. The dihedral angle formed by the naphthalene ring system and the benzene ring is 2.97 (11)°. The hydroxy group is involved in an intramolecular O—H...O hydrogen bond. In the crystal, weak C—H...O hydrogen bonds link the molecules into chains along [001].
