title: 2-Amino-4,6-dimethyl-pyrimidinium dihydrogenphosphate.
abstract: In the crystal structure of the title compound, C(6)H(10)N(3) (+)·H(2)PO(4) (-), the cations and anions are linked by inter-molecular O-H⋯O and N-H⋯O hydrogen bonds, forming a two-dimensional network. Additional stabilization is provided by weak inter-molecular C-H⋯O inter-actions. N-H⋯N inter-actions are also present.
