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

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