Abstract: The title compound, C₂₆H₂₂O₄, is a derivative of 1,4-bis(phenylethynyl)benzene substituted by four methoxy groups at the terminal benzene rings. The asymmetric unit consists of two half-molecules; one centrosymmetric molecule is planar but the other is non-planar, with dihedral angles of 67.7 (1)° between the central benzene ring and the terminal benzene rings. In the crystal structure, molecules form a zigzag molecular network due to - [the interplanar and centroid-centroid distances between the benzene rings are 3.50 (1) and 3.57 (1) Å, respectively] and C-H interactions (2.75 Å). Introduction of the four methoxy groups results in the supramolecular architecture.
