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)}, C19H24N22+·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].
