Cinnarizinium picrate.

In the title salt {systematic name: 4-diphenyl-methyl-1-[(E)-3-phenyl-prop-2-en-1-yl]piperazin-1-ium 2,4,6-trinitro-pheno-late), C(26)H(29)N(2) (+)·C(6)H(2)N(3)O(7) (-), the cinnarizinium cation is protonated at the piperazine N atom connected to the styrenylmethyl group; the piperazine ring adopts a distorted chair conformaiton. In the crystal, bifurcated N-H⋯(O,O) hydrogen bonds link the components into two-ion aggregates.
