Abstract
The asymmetric unit of the title compound, C20H14N4·CH4O, contains two independent half-molecules, each located on an inversion centre, and a methanol solvent molecule. The benzimidazolyl groups form different dihedral angles [24.0 (1) and 11.6 (1)°] with the plane of the central benzene ring in the two molecules. In the crystal, a two-dimensional network is formed through N—H⋯ N, N—H⋯O and O—H⋯N hydrogen-bonding interactions between the benzimidazole units and methanol solvent molecules. π–π stacking interactions also occur between the benzimidazole rings of adjacent molecules, with centroid–centroid distances of 3.720 (14) Å and interplanar distances of 3.53 (1) Å .
