Triethyl-ammonium 4-(3,5-dinitro-benzamido)-N-(3,5-dinitro-benzo-yl)benzene-sulfonamidate.

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?].
