N2 - In the title compound, C14H23N6O2+.HSO4-.H2O, the pyrimidinium ring of the cation adopts a twist-boat conformation, induced by steric clashes between adjacent ring substituents; the anions and the water molecules are linked by three O-H...O hydrogen bonds [H...O=1.70-1.78 Angstrom, O...O=2.548 (2)-2.761 (2) Angstrom and O-H...O=161-168degrees] into chains of edge-fused R-4(4) (12) rings, which are linked into sheets by the cations, via three N-H...O hydrogen bonds [H...O=1.96-2.17 Angstrom, N...O=2.820 (2)-2.935 (2) Angstrom and N-H...O=145-173degrees].
