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 A and C...O distances ranging from 3.157 (3) to 3.567 (3) A. The various interaction chains from a three-dimensional network. The intramolecular angle between the biphenyl ring planes (twist angle) is 71.3 (1) degree.
