The crystal structure of the 1:1 proton‐transfer compound of 8‐aminoquinoline with toluene‐4‐sulfonic acid, viz . quinolin‐8‐aminium toluene‐4‐sulfonate, C 9 H 9 N 2 + ·C 7 H 7 O 3 S − , is different from previously characterized proton‐transfer compounds of 8‐aminoquinoline, in that the 8‐amino group rather than the quinoline N atom is protonated. All H atoms of this aminium group are subsequently involved in intermolecular hydrogen‐bonding interactions with sulfonate O‐atom acceptors, linking the cationic and anionic species and forming a linear polymer structure.
