7-Chloro-4-[(E)-(3-chloro-benzyl-idene)hydrazinyl]-1?-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 ?-? inter-actions [centroid-centroid distance = 3.5625?(13)?Å].
