In the title salt, C6H13N2O+�C6H2N3O7 systematic name: 4- acetylpiperazin-1-ium 2,4,6-trinitrophenolate), the piperazin- 1-ium ring has a slightly distorted chair conformation. In the picrate anion, the mean planes of the two o-NO2 and p-NO2 groups are twisted with respect to the benzene ring by 15.0 (2), 68.9 (4) and 4.4 (3)�, respectively. In the crystal, N—H� � �O hydrogen bonds are observed, linking the ions into an infinite chain along [010]. In addition, weak cation–anion C—H� � �O intermolecular interactions and a weak �–� stacking interaction between the benzene rings of the anions, with an intercentroid distance of 3.771 (8) A ˚ , help to stabilize the crystal packing, giving an overall sheet structure lying parallel to (100). Disorder was modelled for one of the O atoms in one of the o-NO2 groups over two sites with an occupancy ratio of 0.57 (6):0.43 (6)
