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

摘要

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