C-H⋯O interactions in dimethyl 6,6′-dimethoxy-3,3′,5,5′-tetramethylbiphenyl-2,2′- dicarboxylate

The title compound, C₂₂H₂₆O₆, crystallized in the centrosymmetric space group Pbcn with half of the molecule as the asymmetric unit (the molecular symmetry is 2). The H atoms of each of the four methyl groups in the asymmetric unit are disordered over two sites. Nine leading C-H⋯O interactions are present, with H⋯O distances ranging from 2.50 to 2.87 Å and C⋯O distances ranging from 3.157 (3) to 3.567 (3) Å. The various interaction chains form a three-dimensional network. The intramolecular angle between the biphenyl ring planes (twist angle) is 71.3 (1)°.
