Abstract: 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.
