چکیده
The benzene rings in the title compound, C(20)H(22)O(3), form a dihedral angle of 10.39 (8)°. Overall, the mol-ecule is approximately planar with the exception of one of the terminal methyl groups; excluding this group, the r.m.s. deviation for the remaining 22 non-H atoms is 0.0968 Å. The conformation about the C=C bond is E, and an intra-molecular O-H⋯O hydrogen bond leads to the formation of an S(6) motif. In the crystal, linear supra-molecular chains are formed along the a axis via C-H⋯O contacts, and these are connected into double chains via C-H⋯π inter-actions.
