چکیده
The asymmetric unit of the title compound, C(9)H(7)N(7)·2H(2)O, comprises three formula units. The dihedral angles between the triazole rings and the respective central pyridine rings are 4.87 (16)/1.39 (17), 6.46 (16)/7.61 (16) and 7.00 (16)/3.77 (17)°. The water mol-ecules form O-H⋯O hydrogen bonds between themselves and O-H⋯N hydrogen bonds with the N-atom acceptors of the triazole rings, producing a three-dimensional framework.
