title: 4-Chloro-anilinium (4-chloro-phen-yl)guanidinium dichloride hemihydrate.
abstract: In the title hydrated molecular salt, C(6)H(7)ClN(+)·C(7)H(9)ClN(3) (+)·2Cl(-)·0.5H(2)O, the water O atom lies on a crystallographic twofold axis. In the crystal, inter-molecular N-H⋯Cl and O-H⋯Cl hydrogen bonds form layers perpendicular to the ac plane in which both the water mol-ecule and the chloride anion are involved in connecting the layers into a three-dimensional structure.
