7-Chloro-4-[(E)-(3-chlorobenzylidene)hydrazinyl]-1λ4- quinolinium 3-chlorobenzoate

Abstract

The title salt, C16H12Cl2N3+·C7H4ClO2-, features a non-planar cation, the dihedral angle between the quinolinium and benzene residues being 18.98 (10)°. The cation adopts an E conformation about the C - N bond, and the amine group is oriented towards the quinolinium residue. In the crystal, N - H⋯O hydrogen bonds link two cations with two anions, forming a 20-membered {⋯OCO⋯HNC3NH}2 synthon. The dimeric units are connected into a linear supra-molecular chain along [100] via π-π inter-actions [centroid-centroid distance = 3.5625 (13) Å].
