S. Dufresne, M. Gaultois and W. G. Skene

Abstract: In the title compound, 2C₆H₁₆N⁺·C₁₄H₁₂N₂O₆S₂^2-, the anion possesses a crystallographically imposed centre of symmetry. The stilbene group adopts an E configuration, and the two benzene rings are each twisted from its mean plane by 16.05 (10)°. The crystal packing exhibits N-HO hydrogen bonds, which link the anions into two-dimensional layers parallel to the plane formed by the b+c and a vectors, with protruding (up and down) triethylammonium cations.
