Triprolidinium dipicrate

Abstract

In the tripodinium cation of the title compound {systematic name: 2-[(E)-1-(4-methylphenyl)-3-(pyrrolidin-1-ium-1-yl)prop-1-enyl]pyridinium bis(2,4,6-trinitrophenolate)}, C 19H 24N 2+·2C 6H 2N 3O 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 cationanion hydrogen bonds and weak intermolecular N - H⋯O interactions 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 intermolecular π-π [centroidcentroid distance = 3.8036 (14) Å] and C - H⋯O interactions.
