Abstract: The title compound, C₁₉H₂₀O₆, is composed of two individual vanillin subunits bonded to a central chain of C atoms. The molecule lies on a twofold rotation axis. The two aromatic rings are approximately perpendicular to each other and both make a dihedral angle of 53.36 (4)° with the backbone chain. A weak C-H interaction consolidates the crystal packing.
