Abstract

In the title hydrated salt [systematic name: 1-(1,3-benzodioxol-5-ylmeth­yl)piperazin-1-ium 4-nitro­benzoate monohydrate], C12H17N2O2+·C7H4NO4-·H2O, the piperazinium ring of the cation adopts a slightly distorted chair conformation. The piperonyl and piperazine rings are rotated with respect to each other with an N-C-C-C torsion angle of 45.6 (2)°. In the anion, the nitro group is almost coplanar with the adjacent benzene ring, forming a dihedral angle of only 3.9 (4)°. In the crystal, the cations, anions and water mol­ecules are linked through N-H...O and O-H...O hydrogen bonds into chains along the a axis. In addition, weaker inter­molecular C-H...O inter­actions are also observed within the chains. The anions form centrosymmetric couples through [pi]-stacking inter­actions, with an inter­centroid distance of 3.681 (4) Å between the benzene rings.
