(E)-1-(4-Fluoro-2-hy-droxy-phen-yl)-3-(2,3,4-tri-meth-oxy-phen-yl)prop-2-en-1-one

Abstract

In the title mol-ecule, C₁₈H₁₇FO₅, the conformation about the C=C bond of the central enone group is trans. The dihedral angle between the benzene rings is 13.08 (3)°. The hy-droxy group attached to the benzene ring is involved in an intra-molecular O-H⋯O hydrogen bond. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules into chains along [001].

Keywords: C—H⋯O hydrogen bonds; chalcone; crystal structure; dihedral angle.
