Cinnarizinium dipicrate

In the cinnarizinium dication of the title compound {systematic name: 1-diphenyl­methyl-4-[(2E)-3-phenyl­prop-2-en-1-yl]piperazine-1,4-diium bis­(2,4,6-trinitro­phenolate)}, C(26)H(30)N(2) (2+)·2C(6)H(2)N(3)O(7) (−), the piperazine group is protonated at both N atoms and adopts a slightly distorted chair conformation. Strong N—H⋯O(hy­droxy) cation–anion hydrogen bonds link the dication and two anions. In the cation, the (2E)-3-phenyl­prop-2-en-1-yl fragment is disordered over two positions in a ratio of 0.586 (4): 0.414 (4). Two nitro groups in one anion and three in the other one demonstrate rotational disorder. The crystal packing is stabilized by weak inter­molecular π–π [centroid–centroid distances = 3.844 (7), 3.677 (9), 3.825 (5), 3.634 (2) and 3.729 (7) Å], C—H⋯π and C—H⋯O inter­actions.
