In the title compound, 2C(11)H(10)N(3)O(4)S(+)·SiF(6) (2-), the short C-N distance [1.386 (2) Å] is indicative of a slight conjugation of N with the π electrons of the pyridinium ring, and with those of the sulfonyl group. The dihedral angle between the benzene and pyridinium rings is 77.48 (7)°. The crystal structure is stabilized by N-H⋯F and C-H⋯F hydrogen bonds. The Si atom of the anion lies on a special position.
在标题化合物2C₁₁H₁₀N₃O₄S⁺·SiF₆²⁻中，较短的C-N键长[1.386 (2) Å]表明N与吡啶鎓环的π电子以及磺酰基的π电子存在轻微共轭。苯环和吡啶鎓环之间的二面角为77.48 (7)°。晶体结构通过N-H⋯F和C-H⋯F氢键得以稳定。阴离子中的Si原子位于一个特殊位置。
