Piperazine-1,4-diium bis(4-nitrobenzoate) dihydrate

Abstract

The asymmetric unit of the title molecular salt, C4H12N22+·2C7H4NO4− ·2H2O, is composed of half a protonated piperazine dication, located about an inversion center, a benzoate anion and a water molecule of crystallization. In the crystal, the various units are linked by N—H...O, O—H...O and C—H...O hydrogen bonds, forming a supramolecular three-dimensional framework.
