Abstract
The title compound, C24H24N2O4·CH3CN, a disubstituted benzimidazole, crystallized as an acetonitrile monosolvate. The benzene ring of the 2-ethoxy-6-methylphenol substiuent is approximately perpendicular to the nearly planar benzimidazole ring system [maximum deviation = 0.016 (1) Å], making a dihedral angle of 84.27 (8)°. The benzene ring of the 2-ethoxyphenol substituent is inclined to the benzimidazole mean plane by 29.68 (8)°. The dihedral angle between the benzene rings is 80.36 (9)°. In the molecule, there are strong O—H⋯N and O—H⋯O hydrogen bonds. In the crystal, molecules are connected by bifurcated O—H⋯(O,O) hydrogen bonds, forming chains propagating along [010].
