2-Amino­pyrimidin-1-ium 4-methyl­benzene­sulfonate

M. Tabatabaee and N. Noozari

Abstract: In the crystal structure of the title compound, C4H6N3+·C7H7O3S-, inter­molecular 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 inter­molecular [pi]-[pi] stacking inter­action 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
