title: 4-[(E)-2-(2,4-Dichloro-benzyl-idene)hydrazin-1-yl]quinolin-1-ium chloride monohydrate.
abstract: In the title hydrated salt, C(16)H(12)Cl(2)N(3) (+)·Cl(-)·H(2)O, there is a small twist in the cation as seen in the torsion angle linking the benzene ring to the rest of the mol-ecule [171.96 (17)°]. In the crystal, the quinolinium H atom forms a hydrogen bond to the lattice water mol-ecule, which also forms hydrogen bonds to two Cl(-) anions. Each Cl(-) ion also accepts a hydrogen bond from the hydrazine H atom. The three-dimensional architecture is also stabilized by π-π inter-actions between centrosymmetrically related quinoline residues [centroid-centroid distance = 3.5574 (11) Å].
