摘要
The title compound, C21H18O4, exists in the crystal as hydrogen-bonded dimers, O-H...O = 2.669 (3) angstrom. The molecule has normal dimensions. The C=O bond of the CO2H group is conjugated with the C11=C12 double bond [C=C-C=O torsion angle -164.4 (3)-degrees, cos 2(angle) 0.931. but the C=O bond of the CO2C3H7 group is not conjugated [C=C-C=O 65.6 (3)-degrees, cos2 (angle) 0.17].
