In the title compound, C20H26O8, the molecules adopt a conformation in which the torsion angle C(aryl)-C-C-O(aryloxy) is -70.8(2)° and the torsion angle C(aryl)-O-C-C(benzylic) is -152.71(18)°, leading to a C(aryl)...C(aryl) distance of 4.426(3)Å. This distance is identical, within experimental error, 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 64.13(7)°. The conformation is compared with those of related lignin model compounds. The hydrogen-bonding pattern reveals intramolecular interactions, and the formation of centrosymmetric dimers and chains of molecules by intermolecular interactions.
