Abstract: In the crystals of the title compound, C₁₉H₂₄O₇, the molecules adopt a conformation in which the torsion angle C(aryl)-C-C-O(aryloxy) is -70.5  (2)° and the torsion angle C(aryl)-O-C-C(benzylic) is -148.25  (19)°. This leads to a closest C(aryl)C(aryl) distance of 4.319  (3)  Å. This distance is, within experimental error, identical to the calculated maximum value obtained when the torsion angle C(aryl)-O-C-C(benzylic) is varied and the torsion angle C(aryl)-C-C-O(aryloxy) is kept constant. The angle between the aromatic ring planes is 75.79  (7)°. The hydrogen-bonding pattern reveals intramolecular interactions and formation of ribbons of molecules, parallel to the a axis.
