Abstract: In the title compound, C21H18O4, the outer benzyl rings are disordered over two resolved positions in a 0.50 ratio. The O-CH2 groups form dihedral angles of 4.1 (2) and 10.9 (4)° with the central benzene ring, adopting a syn-anti conformation with respect to this ring. In the crystal, the molecules are linked by O-H
O hydrogen bonds and weak C-H
O interactions, forming chains along [010].
