4-Chloroanilinium (4-chlorophenyl)guanidinium dichloride hemihydrate

In the title hydrated molecular salt, C6H7ClN+·C7H9ClN3+·2Cl−·0.5H2O, the water O atom lies on a crystallographic twofold axis. In the crystal, intermolecular N—H...Cl and O—H...Cl hydrogen bonds form layers perpendicular to the ac plane in which both the water molecule and the chloride anion are involved in connecting the layers into a three-dimensional structure
