摘要：

The title molecule, C22H22O4, is centrosymmetric with an inversion centre located at the centre of the benzene ring. The 3,4-dimethoxybenzene fragment is essentially planar [maximum deviation = 0.400 (2) angstrom] and twisted relative to the central benzene ring, forming a dihedral angle of 21.25 (7)degrees. In the crystal, C-H center dot center dot center dot O hydrogen bonds link the molecules into a two-dimensional polymeric structure lying parallel to (100).
