Abstract: 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-HO hydrogen bonds, forming inversion dimers with an R22(14) ring motif. The dimers are linked via O-HO and C-HO hydrogen bonds, forming undulating two-dimensional networks lying parallel to (10-1). These networks are linked by further C-HO hydrogen bonds, forming a three-dimensional structure.
