Abstract
The asymmetric unit of the title compound, C17H20ClN2 +·C6H2N3O7 −·H2O, contains a piperazin-1-ium cation, a picrate anion and one solvent water molecule. The piperazene ring is protonated at one N atom and adopts a highly distorted chair conformation with the chloropheny(phenyl)methyl substituent on the second N atom in an equatorial position. The crystal structure is stabilized by O—H⋯O, N—H⋯O and C—H⋯O hydrogen bonds.
