2,5-Dichloroanilinium 4-chlorobenzenesulfonate
K. Shakuntala,Sabine Foro,B. Thimme Gowda
Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811010518
Abstract: In the crystal of the title compound, C6H6Cl2N+·C6H4ClO3S , the 2,5-dichloroanilinium cations and 4-chlorobenzenesulfonate anions are located on a crystallographic mirror plane and are connected by N—H...O hydrogen bonds. In the crystal, the connectivity of the hydrogen bonds leads to double chains propagating in [010].
4-Chloro-N-phenylbenzenesulfonamide
K. Shakuntala,Sabine Foro,B. Thimme Gowda
Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811015108
Abstract: In the crystal of the title compound, C12H10ClNO2S, the asymmetric unit contains two independent molecules. The N—C bonds in the C—SO2—NH—C segments have gauche torsions with respect to the S=O bonds. The molecules are twisted at the S atoms with C—SO2—NH—C torsion angles of 53.8 (3) and 63.4 (3)° in the two molecules. The benzene rings are tilted relative to each other by 69.1 (1) and 82.6 (1)°. The dihedral angle between the sulfonyl benzene rings of the two independent molecules is 23.7 (2)°. The crystal structure features inversion-related dimers linked by N—H...O hydrogen bonds.
N-(2-Methylphenylsulfonyl)acetamide
K. Shakuntala,Sabine Foro,B. Thimme Gowda
Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811014218
Abstract: In the molecular structure of the title compound, C9H11NO3S, the N—H and C=O bonds are anti to each other, while the amide H atom is syn with respect to the ortho-methyl group in the benzene ring. The C—S—N—C torsion angle is 58.2 (2)°, indicating a twist in the molecule. In the crystal, N—H...O hydrogen bonds link the molecules into chains along the c axis.
4-Chloro-N-(3-chlorophenyl)benzenesulfonamide
K. Shakuntala,Sabine Foro,B. Thimme Gowda

Abstract: In the crystal of the title compound, C12H9Cl2NO2S, the molecule is twisted at the S atom with a C—SO2—NH—C torsion angle of 58.4 (3)°. Furthermore, the N—H bond in this segment is anti to the meta-chloro group. The dihedral angle between the aromatic rings is 77.1 (1)°. The crystal structure features inversion-related dimers linked by N—H...O hydrogen bonds.
N-(2-Chlorophenylsulfonyl)acetamide
K. Shakuntala,Sabine Foro,B. Thimme Gowda
Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811012785
Abstract: The asymmetric unit of the title compound, C8H8ClNO3S, contains two independent molecules in which the C—S—N—C torsion angles are 71.7 (3) and 61.2 (3)°. The benzene rings and the SO2—NH—CO—C segments form dihedral angles of 80.2 (1) and 88.1 (2)° in the two independent molecules. In the crystal, intermolecular N—H...O hydrogen bonds link the molecules into chains in the b-axis direction.
N-(3,4-Dichlorophenyl)-4-methylbenzenesulfonamide
K. Shakuntala,Sabine Foro,B. Thimme Gowda
Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536810051305
Abstract: In the title compound, C13H11Cl2NO2S, the conformation of the N—C bond in the C—SO2—NH—C segment has gauche torsions with respect to the S=O bonds. The molecule is bent at the S atom with a C—SO2—NH—C torsion angle of 64.3 (4)°. Furthermore, the conformation of the N—H bond and the meta-chloro group in the adjacent benzene ring are anti to each other. The two benzene rings are tilted relative to each other by 82.5 (1)°. In the crystal, molecules are linked by pairs of N—H...O(S) hydrogen bonds, forming inversion dimers.
