Abstract
The title compound, C9H7IN+·Cl−·2H2O, was obtained during the synthesis of 8-iodoquinoline from 8-aminoquinoline using the Sandmeyer reaction. The 8-iodoquinolinium ion is almost planar. Solvent water molecules and chloride ions form a hydrogen-bonded chain along the c axis via O—H⋯Cl links. The 8-iodoquinolinium ions, which are packed along the c axis with cationic aromatic π–π stacking (centroid–centroid distance = 3.624 Å), are linked to the chain via N—H⋯O hydrogen bonds.
