4-[(4-Chloro-phen-yl)(phen-yl)-meth-yl]-piperazin-1-ium picrate monohydrate
Abstract:
The asymmetric unit of the title compound, C(17)H(20)ClN(2) (+)·C(6)H(2)N(3)O(7) (-)·H(2)O, contains a piperazin-1-ium cation, a picrate anion and one solvent water mol-ecule. The piperazene ring is protonated at one N atom and adopts a highly distorted chair conformation with the chloro-pheny(phen-yl)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.
