title: 7-Chloro-4-[(E)-(3-chloro-benzyl-idene)hydrazinyl]-1λ-quinolinium 3-chloro-benzoate.
abstract: The title salt, C(16)H(12)Cl(2)N(3) (+)·C(7)H(4)ClO(2) (-), 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⋯HNC(3)NH}(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].
