title: Crystal structure of (E)-3-{[2-(2,4-di-chloro-benzyl-idene)hydrazin-1-yl]carbon-yl}pyridinium chloride trihydrate.
abstract: In the title hydrated salt, C13H10Cl2N3O(+)·Cl(-)·3H2O, the organic cation exhibits a dihedral angle of 8.26 (14)° between the mean planes of the pyridinium and benzene rings, and dihedral angles of 8.70 (15) and 15.93 (5)° between the mean planes of the hydrazide group and the benzene and pyridinium rings, respectively. In the crystal, N-H⋯O, N-H⋯Cl, C-H⋯O, C-H⋯Cl, O-H⋯O, O-H⋯N and O-H⋯Cl hydrogen bonds link the complex cations, chloride anions and solvent water mol-ecules into a three-dimensional network.
