6,6'-Dimethoxy-3,3',5,5'-tetramethylbiphenyl-2,2'-dimethanol.
The title compound, C20H26O4, crystallized in the centrosymmetric space group P21/c with a single molecule as the asymmetric unit. The two hydroxyl-H atoms are ordered and are involved in hydrogen bonds whose OD...OA distances are 2.807 (2) and 2.805 (2) A; one of these bonds is intramolecular. The intramolecular dihedral angle between the ring planes (twist angle) is 87.3 (1) degree.
