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.
