چکیده
In the title hydrated mol-ecular salt, 2C5H8N3O(+)·SO4 (2-)·H2O, the components are linked by N-H⋯Os and Ow-H⋯Os (s = sulphate, w = water) hydrogen bonds, generating a layer by a+b+c and 2a-b translations. The cations are arranged nearly in parallel and show displaced π-π stacking centroid-centroid distance = 4.661 (2) Å between adjacent layers.

In the title salt, C4H7N4O(+)·C7H7O3S(-), the 2,6-di-amino-4-oxo-1,3-di-hydro-pyrimidin-1-ium cation inter-acts with the sulfonate group of the p-toluene-sulfonate anion via a pair of N-H⋯O hydrogen bonds, forming a hetero-synthon R 2 (2)(8) that mimics the role of a carboxyl-ate. The self-assembled cations form a homo-synthon R 2 (1)(6) motif which is further linked with the sulfonate anion vi...
