Crystal structure of 3-benzamido-1-(4-nitrobenzyl)quinolinium trifluoromethanesulfonate

In the title compound, C23H18N3O3+center dot 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 14.90 (2) and 31.66 (2)degrees. The quinolinium and phenyl rings are slightly twisted with respect to each other at dihedral angles of 6.99 (4) and 8.54 (4)degrees. The trifluoromethanesulfonate anions are linked to the organic cations via N-H center dot center dot center dot O hydrogen-bonding interactions involving the NH amide groups. In the crystal, the organic cations are linked by weak C-H center dot center dot center dot O(nitro group) interactions into supramolecular chains propagating along the b-axis direction.
