چکیده
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).

In the title compound, C(15)H(10)Cl(2)O(2), the dihedral angle between the mean planes of the two benzene rings is 7.7 (6)°. The crystal packing is influenced by O-H⋯O hydrogen bonds, which form chains along [010]. Weak π-π stacking inter-actions [centroid-centroid distance = 3.6697 (13) Å] are observed, which may contribute to the crystal packing stability.
