Acta Crystallogr Sect E Struct Rep Online. 2009 Feb 28;65(Pt 3):o614. doi: 10.1107/S1600536809006412.

Abstract

In the crystal structure of the title salt, C(6)H(6)NO(2) (+)·C(6)HCl(2)O(4) (-), 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-H⋯O and O-H⋯O hydrogen bonds, forming a supra-molecular ladder. C-H⋯O inter-actions are also present.
