In the title compound, C19H13N5·C4H8O2·2H2O, the molecular skeleton of the 2,6-bis(benzimidazol-2-yl)pyridine (bbip) molecule is essentially planar (r.m.s. deviation = 0.023 Å). An extensive three-dimensional network of intermolecular N—H⋯O, O—H⋯O and O—H⋯N hydrogen bonds consolidates the crystal packing, which also exhibits π–π interactions between the five- and six-membered rings from neighbouring bbip molecules.
