ABSTRACT
In the title compound, C23H18N3O3 (+)·CF3SO3 (-), the asymmetric unit contains two crystallographically independent organic cations with similar conformations. Each cation shows a moderate distortion between the planes of the amide groups and the quinolinium rings with dihedral angles of 14.90â (2) and 31.66â (2)°. The quinolinium and phenyl rings are slightly twisted with respect to each other at dihedral angles of 6.99â (4) and 8.54â (4)°. The tri-fluoro-methane-sulfonate anions are linked to the organic cations via N-Hâ¯O hydrogen-bonding inter-actions involving the NH amide groups. In the crystal, the organic cations are linked by weak C-Hâ¯O(nitro group) inter-actions into supramol-ecular chains propagating along the b-axis direction.
