Abstract: The asymmetric unit of the title compound, C22H22O4, consists of two independent molecules (A and B). The cyclohexene rings adopt slightly distorted sofa conformations in both molecules. The dihedral angles between the benzene rings are 74.16 (13) and 71.85 (13)° in molecules A and B, respectively. In the crystal, weak C-HO hydrogen bonds link the molecules into a ribbon-like structure along the b axis. Weak C-H interactions are also observed.
