Abstract
The title compound, C9H7IN+·I3 −·C4H8O, was synthesized from 8-aminoquinoline using the Sandmeyer reaction. The 8-iodoquinolinium cation is essentially planar and the triiodide ion is almost linear. N—H⋯O hydrogen bonds, and intermolecular I⋯I [3.7100 (5) Å] and I⋯H interactions, between the cation, anion and solvent molecules result in the formation of sheets oriented parallel to the (03) plane. Between the sheets, 8-iodoquinolinium and triiodide ions are stacked alternately, with I⋯C distances in the range ∼3.8–4.0 Å.
