The crystal structure of 3,3′-dimethoxybiphenyl has been determined by X-ray diffraction methods with an aim of describing the hydrogen interaction in biphenyl derivatives. The title compound crystallizes in monoclinic space group 𝑃21/𝑐 with unit cell dimensions, 𝑎 = 7.706(1), 𝑏 = 11.745(2), 𝑐 = 12.721(2) Å, 𝛽 = 92.31(1)°, 𝑍 = 4 and its structure has been refined up to the reliability index of 3.8%. The average torsion angle about the inter-ring C–C bond is 37.5°. The O1 and O1′ atoms of the methoxy group are deviated by 0.046(1) Å and 0.234(1) Å from the mean planes of respective rings. The crystal cohesion is pronounced due to three-inter-molecular C–H…O hydrogen bonds.
