2-(Benzene-sulfonamido)pyridinium nitrate.

ABSTRACT: In the title compound, C(11)H(11)N(2)O(2)S(+)·NO(3) (-), the dihedral angle between the benzene and pyridinium rings is 87.59?(8)°. An intra-molecular C-H?O inter-action occurs in the cation. In the crystal structure, ion pairs occur, being linked by two strong N-H?O inter-actions, forming R(2) (2)(8) loops. The packing is further stabilized by weak C-H?O inter-actions.

4-(2-Nitro-benzene-sulfonamido)pyridinium nitrate.

Project description: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.

2-(Benzene-sulfonamido)pyridinium perchlorate.

Project description:In the title compound, C(11)H(11)N(2)O(2)S(+)·ClO(4) (-), the dihedral angle between the benzene and pyridinium rings is 87.33?(10)°. An intra-molecular N-H?O inter-action, with an S=O-bonded O atom as receptor, occurs in the cation. In the crystal structure, ion pairs occur, being linked by strong N-H?O hydrogen bonds. The perchlorate anion plays a further role in the mol-ecular packing by accepting several weak C-H?O inter-actions.

N-Acetyl-4-(benzene-sulfonamido)benzene-sulfonamide.

Project description:In the mol-ecule of the title compound, C(14)H(14)N(2)O(5)S(2), the dihedral angle between the aromatic rings is 77.75 (9)°.
