چکیده
The mol-ecule of the title compound, C(17)H(16)O(3), exists in the E conformation with respect to the central C=C bond, is almost planar(r.m.s. deviation = 0.003 Å) and has an intra-molecular O-H⋯O hydrogen bond, which generates an S(6) ring. In the crystal, mol-ecules are linked by C-H⋯O inter-actions.
