It has been confirmed that mercaptopyridines undergo spontaneous condensation in redox reaction with iodine-forming dithiopyridines. In the solid state, these compounds are protonated at the N atoms and cocrystallize with iodine forming salt structures, namely, 2-[(pyridin-2-yl)disulfanyl]pyridinium triiodide sesquiiodine, C10H9N2S2+·I3-·1.5I2, and 4,4′-(disulfanediyl)dipyridinium pentaiodide triiodide, C10H10N2S22+·I5-·I3-. Dithiopyridine cations are packed among three-dimensional frameworks built from iodide anions and neutral iodine mols., and are linked by hydrogen, halogen and chalcogen interactions. Quantum chem. computations indicated that dithiopyridines exhibit anomalously high nitrogen basicity which qualify them as potential proton sponges.
