چکیده
In the title compound, C(21)H(24)O(3), the enone group adopts an s-cis conformation. The planes of the aromatic rings are inclined at an angle of 6.1 (1)°. The alk-oxy tail is not linear, with the maximum deviation from the least-squares plane being 0.375 (2) Å. Mol-ecules are connected into extended chains along the a axis through O-H⋯O(carbon-yl) hydrogen bonds and are inter-linked via C-H⋯O inter-actions to form a two-dimensional array parallel to the ab plane.
