2-(2,4-Dinitro-benz-yl)pyridinium 2-hy-droxy-3,5-dinitro-benzoate.

ABSTRACT: In the structure of the title salt, C(12)H(10)N(3)O(4) (+)·C(7)H(3)N(2)O(7) (-), the cations and the anions are linked by a single N(+)-H⋯O(carbox-yl) hydrogen bond, the discrete cation-anion unit having no inter-molecular associations other than weak cation-anion aromatic ring π-π inter-actions [ring centroid separation = 3.7320 (14) Å] and a number of weak inter-unit aromatic C-H⋯O contacts. An intramolecular C-H⋯O hydrox-yl-carboxyl hydrogen bond occurs in the anion.
