(2E)-1-(3,5-Di­hydroxy­phen­yl)-3-(4-meth­oxy­phen­yl)prop-2-en-1-one

In the title compound, C₁₆H₁₄O₄, the benzene rings are inclined to one another by 4.91 (7)°. The conformation about the C=O and C=C bonds is trans and cis, respectively. In the crystal, mol­ecules are linked by O—H...O hydrogen bonds, forming inversion dimers with an R₂²(14) ring motif. The dimers are linked via O—H...O and C—H...O hydrogen bonds, forming undulating two-dimensional networks lying parallel to (10-1). These networks are linked by further C—H...O hydrogen bonds, forming a three-dimensional structure.
