Abstract
In the triprolidinium cation of the title compound {systematic name: 2-[1-(4-methylphenyl)-3-(pyrrolidin-1-ium-1-yl)prop-1-en-1-yl]pyridin-1-ium bis(2,5-dichloro-4-hydroxy-3,6-dioxocyclohexa-1,4-dien-1-olate)–2,5-dichloro-3,6-dihydroxycyclohexa-2,5-diene-1,4-dione–methanol–water (2/1/2/2)}, C19H24N2 2+·2C6HCl2O4 −·0.5C6H2Cl2O4·CH3OH·H2O, the N atoms on both the pyrrolidine and pyridine groups are protonated. The neutral chloranilic acid molecule is on an inversion symmetry element and its hydroxy H atoms are disordered over two positions with site-occupancy factors of 0.53 (6) and 0.47 (6). The methanol solvent molecule is disordered over two positions in a 0.836 (4):0.164 (4) ratio. In the crystal, N—H⋯O, O—H⋯O and C—H⋯O interactions link the components. The crystal structure also features π–π interactions between the benzene rings [centroid–centroid distances = 3.5674 (15), 3.5225 (15) and 3.6347 (15) Å].
