Abstract: In the title compound, C₁₉H₁₃N₅·3CH₄O, the 2,6-bis(2-benzimidazolyl)pyridine molecule is essentially planar with an r.m.s. deviation for all non-H atoms of 0.185 Å. The crystal structure is stabilized by intermolecular O-HO, O-HN and N-HO hydrogen bonds and weak [pi] [pi] stacking interactions with centroid-centroid distances of 3.6675 (16) and 3.6891 (15) Å. The atoms of one of the methanol solvent molecules are disordered over two sites with refined occupancies of 0.606(8) and 0.394(8).
