Project description:A short C-N distance [1.394?(2)?Å] in the title compound, C(11)H(10)N(3)O(4)S(+)·NO(3) (-), is indicative of some conjugation of the sulfonamide ? electrons with those of the pyridinium ring. The crystal structure is stabilized by N-H?O hydrogen bonds.

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 ?-electrons with those of the pyridinium ring. The crystal structure is stabilized by N-H?O hydrogen bonds.

Project description: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.

2-{1-[(2-Nitro-benzene-sulfonamido)-meth-yl]cyclo-hexyl}acetic acid.

Project description:In the title compound, C(15)H(20)N(2)O(6)S, the C-SO(2)-NH-C torsion angle is 64.54?(14)°. In the mol-ecule, there is a bifurcated N-H?(O,O) hydrogen bond, forming S(7) rings. In the crystal, inversion dimers are formed via O-H?O hydrogen bonds involving the carboxyl group, so forming R(2) (2)(8) rings. These dimers are further linked via pairs of C-H?O hydrogen bonds, forming a C(6) chain propagating along the c-axis direction.

Project description: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 ? 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.

3-(1H-Indol-3-yl)-2-(2-nitro-benzene-sulfonamido)-propanoic acid including an unknown solvate.

Project description:In the title compound, C(17)H(15)N(3)O(6)S, which crystallized with highly disordered methanol and/or water solvent mol-ecules, the dihedral angle between the the indole and benzene ring systems is 5.3?(2)°, which allows for the formation of intra-molecular ?-? stacking inter-actions [centroid-centroid separations = 3.641?(3) and 3.694?(3)?Å] and an approximate overall U-shape for the mol-ecule. In the crystal, dimers linked by pairs of N(s)-H?O(c) (s = sulfonamide and c = carboxyl-ate) hydrogen bonds generate R(2) (2)(10) loops, whereas N(i)-H?? (i = indole) inter-actions lead to chains propagating in [100] or [010]. Together, these lead to a three-dimensional network in which the solvent voids are present as inter-secting (two-dimensional) systems of [100] and [010] channels. The title compound was found to contain a heavily disordered solvent mol-ecule, which could be methanol or water or a mixture of the two. Due to its uncertain nature and the unresolvable disorder, the data were processed with the SQUEEZE option in PLATON [Spek (2009 ?). Acta Cryst. D65, 148-155], which revealed 877.8?Å(3) of solvent-accessible volume per unit cell and 126 electron-units of scattering density or 109.7?Å(3) (16 electron units) per organic mol-ecule.. This was not included in the calculations of overall formula weight, density and absorption coefficient.
