(E)-1-(2-Hy­droxy-6-meth­oxy­phen­yl)-3-(2,4,6-tri­meth­oxy­phen­yl)prop-2-en-1-one

In the title mol­ecule, C₁₉H₂₀O₆, the conformation about the C=C bond of the central enone group is E. The dihedral angle formed by the benzene rings is 11.6 (2)°. 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 [010].
