title: Adipic acid-2,6-bis-(1H-benzimidazol-2-yl)pyridine-water (1/2/4).
abstract: The asymmetric unit of the title hydrated co-crystal, 2C19H13N5·C6H10O4·4H2O, consists of one 2,6-bis-(1H-benzimidazol-2-yl)pyridine mol-ecule, half of an adipic acid mol-ecule (bis-ected by an inversion center) and two water solvates. In the crystal, N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds and π-π inter-actions [centroid-centroid distances = 3.769 (2) and 3.731 (2) Å] form a three-dimensional supra-molecular structure.
