                                    In 4-[(4-chloro-3-nitrobenzoyl) hydrazinocarbonyl] pyridinium chloride, C13H10ClN4O4+center dot Cl-, the component ions are linked into a three-dimensional framework structure by a combination of three N - H center dot center dot center dot Cl and five C - H center dot center dot center dot O hydrogen bonds. In N-3,5-dinitrobenzoyl-N'-isonicotinoylhydrazine, C13H9N5O6, the molecules are linked into a three-dimensional framework structure by one N - H center dot center dot center dot O and three C - H center dot center dot center dot O hydrogen bonds, augmented by an aromatic pi-pi stacking interaction.
