Triprolidinium dipicrate.

ABSTRACT: In the tripodinium cation of the title compound {systematic name: 2-[(E)-1-(4-methyl-phen-yl)-3-(pyrrolidin-1-ium-1-yl)prop-1-en-yl]pyridinium bis-(2,4,6-trinitro-phenolate)}, C(19)H(24)N(2) (+)·2C(6)H(2)N(3)O(7) (-), the N atoms on both the pyrrolidine and pyridinium groups are protonated. The pyrrolidine group adopts a slightly distorted envelope configuration. Strong N-H?O cation-anion hydrogen bonds and weak inter-molecular N-H?O inter-actions link the dication and two anions. In both picrate anions, the nitro groups display rotational disorder over two orientations in a 0.605?(6):0.395?(6) ratio. The crystal packing also features weak inter-molecular ?-? [centroid-centroid distance = 3.8036?(14)?Å] and C-H?O inter-actions.
