Abstract: The asymmetric unit of the title hydrated co-crystal, 2C₁₉H₁₃N₅·C₆H₁₀O₄·4H₂O, consists of one 2,6-bis(1H-benzimidazol-2-yl)pyridine molecule, half of an adipic acid molecule (bisected by an inversion center) and two water solvates. In the crystal, N-HO, O-HO and O-HN hydrogen bonds and - interactions [centroid-centroid distances = 3.769 (2) and 3.731 (2) Å] form a three-dimensional supramolecular structure.
