title: 2-Amino-pyrimidin-1-ium 4-methyl-benzene-sulfonate.
abstract: In the crystal structure of the title compound, C(4)H(6)N(3) (+)·C(7)H(7)O(3)S(-), inter-molecular N-H⋯O hydrogen bonds link the cations and anions into chains along [100]. Additional stabilization is provided by weak C-H⋯O hydrogen bonds. An inter-molecular π-π stacking inter-action with a centroid-centroid distance of 3.6957 (7) Å is also observed. The H atoms of the methyl group were refined as disordered over two sets of sites with equal occupancies.
