چکیده
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.

In the title compound, C(11)H(10)N(3)O(4)S(+)·Br(-), the benzene ring makes an angle of 88.4 (2)° with the pyridinium ring. The dihedral angle between the nitro group and the benzene ring is 16.5 (2)°. The ions in the crystal structure are linked by a combination of inter-molecular N-H⋯Br and non-conventional C-H⋯Br and C-H⋯O hydrogen bonds, forming a three-dimensional network.

In the title compound, C(11)H(10)N(3)O(4)S(+)·C(2)Cl(3)O(2) (-), the benzene ring forms an angle of 85.21 (13)° with the pyridinium ring. The nitro group is nearly coplanar with its attached benzene ring [dihedral angle = 3.68 (12)°]. In the crystal structure, strong N-H⋯O hydrogen bonds link the ion-pairs. The packing is further consolidated by weak C-H⋯O inter-ations.

There are two mol-ecules in the asymmetric unit of the title compound, C(11)H(10)N(3)O(4)S(+)·NO(3) (-). All bond distances have normal values. The C-N bond distances in the sulfonamide group [1.389 (3) and 1.382 (3) Å] may indicate slight conjugation of the sulfonamide N-atom π-electrons with those of the pyridinium ring. The crystal structure is stabilized by N-H⋯O hydrogen bonds.
