In the title compound, C17H16O4, the dihedral angle between the benzene rings is 21.22 (1)° and the mean plane of the prop-2-en-1-one group makes dihedral angles of 10.60 (1) and 11.28 (1)°, respectively, with those of the hy-droxy-phenyl and eth-oxy-phenyl rings. The eth-oxy substituent forms a dihedral angle of 88.79 (2)° with the the prop-2-en-1-one group, which is found to be slightly twisted. In the crystal, phenolic O-H⋯O hydrogen bonds to the carbonyl O atom form a two-dimensional supra-molecular network structure lying parallel to (010).
在标题化合物C₁₇H₁₆O₄中，苯环之间的二面角为21.22 (1)°，2-丙烯-1-酮基团的平均平面与羟基苯基和乙氧基苯基环的平均平面分别形成10.60 (1)°和11.28 (1)°的二面角。乙氧基取代基与2-丙烯-1-酮基团形成88.79 (2)°的二面角，发现其略有扭曲。在晶体中，酚羟基O-H⋯O与羰基O原子形成氢键，形成平行于(010)的二维超分子网络结构。
