Abstract: The structure of the title compound, C₁₈H₁₈O₄, consists of separate centrosymmetric planar molecules arranged in columns parallel to the monoclinic unique axis. The normal to the mean molecular plane lies at 55.4° to the unique axis, giving adjacent columns with alternating stacking directions. The mean deviation of all non-H atoms from the least-squares molecular plane is 0.064 Å. Bond lengths in the aromatic rings range from 1.347 (2) to 1.440 (2) Å and the two unique Me-O bond distances are 1.418 (2) and 1.419 (2) Å.
