Abstract: In the title salt, C6H10N3O2+·C7H7O3S-, the 2-amino-4,6-dimethoxypyrimidinium cation interacts with the sulfonate group of the p-toluenesulfonate anion via a pair of N-HO hydrogen bonds, forming a cyclic hydrogen-bonded R22(8) motif, which in the crystal is linked by further intemolecular N-HO hydrogen bonds, forming supramolecular chains along the c axis. Furthermore, neighboring chains are interlinked via weak C-HO hydrogen bonds and C-H interactions, forming layers.
