In the structure of the title salt, C20H20NO(+)·C6H4FO3S(-), the 4-(eth-oxy-phen-yl)ethenyl unit is disordered over two positions with a refined site-occupancy ratio of 0.610â
(6):0.390â
(6). The cation is nearly planar, the dihedral angle between the quinolinium and benzene rings being 6.7â
(4) and 1.7â
(7)° for the major and minor components, respectively. The eth-oxy group is essentially coplanar with the benzene ring [C-O-C-Cmethy = 177.1â
(8) and 177.8â
(12)° for the major and minor components, respectively]. In the crystal, cations and anions are linked into chains along the b-axis direction by C-Hâ¯Osulfon-yl weak inter-actions. These chains are further connected into sheets parallel to (001) by C-Hâ¯Osulfon-yl weak inter-actions. The chains are also stacked along the a axis through π-π inter-actions involving the quinolinium and benzene rings [centroid-centroid distances = 3.636â
(5)â
Å for the major component and 3.800â
(9)â
Å for the minor component]. C-Hâ¯π inter-actions are also present.
