H. Ishida

Abstract: In the title compound, bis(3-methyl-2H-pyrazol-1-ium) 2,5-dichloro-3,6-dioxido-1,4-benzoquinone, 2C₄H₇N₂⁺·C₆Cl₂O₄^2-, the chloranilate and 3-methylpyrazolium ions are held together by bifurcated N-HO hydrogen bonds, giving a centrosymmetric chloranilate-3-methylpyrazolium 1:2 unit. The 1:2 units are connected to each other by N-HO hydrogen bonds, forming a molecular ladder.
