Abstract: The molecular structure of the title salt, C6H16N+·C20H11N6O12S-, shows a planar geometry of the benzamido-phenyl-sulfonyl moiety, with a dihedral angle of 1.59 (9)° between the aromatic ring planes. The central ring and the aromatic ring of the other dinitrobenzamide group are nearly perpendicular, making a dihedral angle of 89.55 (9)°. All nitro groups lie almost in plane with the associated aromatic rings, the O-N-C-C torsion angles ranging from 9.2 (2) to 24.3 (2)°. In the crystal, strong anion-anion N-H...O and anion-cation hydrogen bonds form inversion dimers stacked along the a axis. Less prominent anion-anion C-H...O interactions lead to the formation of a three-dimensional network including anion-anion dimers as well as anion-anion chains along [100?].
