title: 2,6-Bis(4H-1,2,4-triazol-4-yl)pyridine dihydrate.
abstract: In the asymmetric unit of the title compound, C(9)H(7)N(7)·2H(2)O, there are two formula units in which the two triazole rings of each of the organic component mol-ecules form dihedral angles of 7.0 (4)/6.9 (4) and 2.7 (4)/3.6 (4)° with the respective central pyridine rings. The four water mol-ecules of solvation form O-H⋯O hydrogen bonds among themselves and O-H⋯N bonds with the N-atom acceptors of the triazine rings, giving a three-dimensional framework structure.
