In 4-[(4-chloro-3-nitrobenzoyl)hydrazinocarbonyl]pyridinium chloride, C₁₃H₁₀ClN₄O₄ ^-·Cl^-, the component ions are linked into a three-dimensional framework structure by a combination of three N-H...Cl and five C-H...O hydrogen bonds. In N-3,5-dinitrobenzoyl-N′- isonicotinoylhydrazine, C₁₃H₉-N₅O₆, the molecules are linked into a three-dimensional framework structure by one N-H...O and three C-H...O hydrogen bonds, augmented by an aromatic π-π stacking interaction.
