Abstract
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, C13H9N5O6, 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.
