Hydro­gen bonds and C—H⋯O interactions in 2,2′-dimethoxybiphenyl-5,5′-dimethanol at 150 K

The title compound, C₁₆H₁₈O₄, crystallized in the centrosymmetric space group P2₁/c with one mol­ecule in the asymmetric unit. The two hydroxyl-H atoms are ordered, and are involved in intermolecular hydrogen bonds with O_donor⋯O_acceptor distances of 2.761 (1) and 2.699 (1) Å, and O—H⋯O angles of 157 (2) and 168 (2)°. Seven leading intermolecular C—H⋯O interactions have H⋯O distances ranging from 2.41 to 2.76 Å and C—H⋯O angles ranging from 125 to 170°. The hydrogen bonds and C—H⋯O interactions form chain and ring patterns, resulting in a richly three-dimensional network. The bi­phenyl twist angle is 67.2 (1)°.
