Abstract:
The mol-ecular structure of the title salt, C6H16N(+)·C20H11N6O12S(-), shows a planar geometry of the benzamido-phen-yl-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 dinitro-benzamide 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 inter-actions lead to the formation of a three-dimensional network including anion-anion dimers as well as anion-anion chains along [100?].

The nitrous acid is unstable. Hence, it is formed in situ from a solution of sodium nitrite and cold aqueous acids such as hydrochloric or sulfuric acid. In an acidic solution, the –OH group of nitrous acid undergoes protonation to give oxonium ion, followed by water loss...
