2,6-Bis(1H-benzimidazol-2-yl)pyridine butyric acid monosolvate dihydrate

摘要

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.
