| Popis: | In the crystal structure of the title compound, C6H10N3+·C7H2I3O2−·C7H3I3O2, two R22(8) motifs are observed. One is generated by the interaction of the 2-amino-4,6-dimethylpyrimidin-1-ium cation with the carboxylate group of the 2,3,5-triiodobenzoate anion via N—H...O hydrogen bonds. The other R22(8) motif is formed by the interaction of two centrosymmentrically related pyrimidine moieties through N—H...N hydrogen bonds. The two motifs combine to form a linear heterotetrameric unit. Heterotetrameric units are linked by a carboxyl–carboxylate O—H...O hydrogen bond (involving the O—H group of neutral 2,3,5-triiodobenzoic acid and an O atom of the anion), forming a supramolecular chain along the a axis. In addition, components are held by weak I...O interactions in the range 3.023 (5) to 3.382 (5) Å and I...I interactions in the range 3.6327 (7) to 4.0025 (8) Å. |
