چکیده
In the title salt, C(6)H(10)N(3)O(2) (+)·C(7)H(7)O(3)S(-), the 2-amino-4,6-dimeth-oxy-pyrimidinium cation inter-acts with the sulfonate group of the p-toluene-sulfonate anion via a pair of N-H⋯O hydrogen bonds, forming a cyclic hydrogen-bonded R(2) (2)(8) motif, which in the crystal is linked by further intemolecular N-H⋯O hydrogen bonds, forming supra-molecular chains along the c axis. Furthermore, neighboring chains are inter-linked via weak C-H⋯O hydrogen bonds and C-H⋯π inter-actions, forming 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...

In the crystal structure of the title compound, C(6)H(10)N(3) (+)·C(7)H(2)I(3)O(2) (-)·C(7)H(3)I(3)O(2), two R(2) (2)(8) motifs are observed. One is generated by the inter-action of the 2-amino-4,6-dimethyl-pyrimidin-1-ium cation with the carboxyl-ate group of the 2,3,5-triiodo-benzoate anion via N-H⋯O hydrogen bonds. The other R(2) (2)(8) motif is formed by the inter-action of two centrosymmen...
