In the title compound, bis(3-methyl-2H-pyrazol-1-ium) 2,5-dichloro-3,6-dioxido-1,4-benzoquinone, 2C4H7N2+·C6Cl2O42−, the chloranilate and 3-methylpyrazolium ions are held together by bifurcated N—H…O hydrogen bonds, giving a centrosymmetric chloranilate–3-methylpyrazolium 1:2 unit. The 1:2 units are connected to each other by N—H…O hydrogen bonds, forming a molecular ladder.
