1-Piperonylpiperazinium 4-chloro-benzoate.
In the title salt {systematic name: 1-[(1,3-benzodioxol-5-yl)meth-yl]piperazin-1-ium 4-chloro-benzoate}, C12H17N2O2 (+)·C7H4ClO2 (-), the piperazine ring adopts a slightly disordered chair conformation. The dioxole ring is in a flattened envelope conformation with the methyl-ene C atom forming the flap. The relative orientation of the piperonyl ring system and the piperazine rings is reflected in the N-C-C C torsion angle of 132.3 (1)°. In the anion, the mean plane of the carboxyl-ate group is twisted from that of the benzene ring by 14.8 (9)°. In the crystal, the components are linked by N-H⋯O and weak C-H⋯O hydrogen bonds, forming chains along [010].
