Bis[4-(2-nitro­benzene­sulfonamido)­pyridinium] hexa­fluoro­silicate

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)°. Th...

Sumario: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.
