2-[(E)-2-(4-Eth-oxy-phen-yl)ethen-yl]-1-methyl-quinolinium 4-fluoro-benzene-sulfonate.

ABSTRACT: 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 0.610?(6):0.390?(6). The cation is nearly planar, the dihedral angle between the quinolinium and benzene rings being 6.7?(4) and 1.7?(7)° for the major and minor components, respectively. The eth-oxy group is essentially coplanar with the benzene ring [C-O-C-Cmethy = 177.1?(8) and 177.8?(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-H?Osulfon-yl weak inter-actions. These chains are further connected into sheets parallel to (001) by C-H?Osulfon-yl weak inter-actions. The chains are also stacked along the a axis through ?-? inter-actions involving the quinolinium and benzene rings [centroid-centroid distances = 3.636?(5)?Å for the major component and 3.800?(9)?Å for the minor component]. C-H?? inter-actions are also present.
