title: Melaminium nitrate-melamine-water (1/1/1).
abstract: In the crystal structure of the title salt, C(3)H(7)N(6) (+)·NO(3) (-)·C(3)H(6)N(6)·H(2)O, the asymmetric unit consists of two neutral melamine (1,3,5-triazine-2,4,6-triamine) mol-ecules, two melaminium cations, two nitrate anions and two solvent water mol-ecules. One of the nitrate anions is disordered over two sets of positions, with a refined occupancy ratio of 0.909 (3):0.091 (3). The cations and neutral mol-ecules are approximately planar, with maximum deviations of 0.018 (2), 0.024 (2), 0.019 (2) and 0.007 (2) Å for each, respectively. In the crystal structure, melaminium cations and netural melamine mol-ecules self-assemble via N-H⋯N hydrogen bonds to form a supra-molecular hexa-gonal-shaped motif. In addition, the nitrate anions and water mol-ecules are connected by N-H⋯O hydrogen bonds to form a three-dimensional network.
