The 8-iodoquinolinium ion is almost planar. Solvent water molecules and chloride ions form a hydrogen-bonded chain along the c axis via O¡ªH...Cl links. The 8-iodoquinolinium ions, which are packed along the c axis with cationic aromatic ¦Ð¨C¦Ð stacking (centroid¨Ccentroid distance = 3.624 ), are linked to the chain via N¡ªH...O hydrogen bonds. %U http://scripts.iucr.org/cgi-bin/paper?S1600536808031528
