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.
