K. Gotoh, H. Nagoshi and H. Ishida

Abstract: In the crystal structure of the title salt, C₆H₆NO₂⁺·C₆HCl₂O₄^-, the pyridine ring and the mean plane of the hydrogen chloranilate anion form a dihedral angle of 77.40 (8)°. The ionic components are held together by N-HO and O-HO hydrogen bonds, forming a supramolecular ladder. C-HO interactions are also present.
