N-(2-Chlorobenzoyl)-4-methylbenzenesulfonamide
In the title compound, C14H12ClNO3S, the C=O bond is syn to the Cl substituent in the adjacent benzene ring. The C—S—N—C torsion angle is −80.6 (6)°. The chlorobenzoyl ring is disordered and was refined using a split model [occupancy ratio 0.537 (3):0.463 (3)]. In the crystal, molecules are linked by pairs of N—H⋯O(S) hydrogen bonds, forming inversion dimers
N-(3-Methylbenzoyl)benzenesulfonamide
The asymmetric unit of the title compound, C14H13NO3S, contains three independent molecules in which the dihedral angles between the sulfonyl and benzoyl benzene rings are 83.3 (2), 84.4 (2) and 87.6 (2)°. In the crystal, molecules are linked into chains running along the a axis via N—H⋯O hydrogen bonds
2-Bromo-N-(2-chlorophenyl)acetamide
The conformation of the N—H bond in the structure of the title compound, C8H7BrClNO, is syn to the 2-chloro substituent in the aniline ring and anti to both the C=O and C—Br bonds in the side chain, similar to that observed in 2-chloro-N-(2-chlorophenyl)acetamide. In the crystal, molecules are linked into chains along the a axis by N—H⋯O hydrogen bonds. These chains are in turn linked into pairs, in the form of columns, through much weaker C—H⋯Cl and Br⋯Br [4.3027 (3) Å] interactions
2-Chloro-N-(2-methylbenzoyl)benzenesulfonamide
In the title compound, C14H12ClNO3S, the N—H bond is antiperiplanar to the C=O bond. The dihedral angle between the two aromatic rings is 78.7 (1)°. The crystal structure features inversion-related dimers linked by pairs of N—H⋯O(S) hydrogen bonds
2-Chloro-N-(4-nitrobenzoyl)benzenesulfonamide
In the title compound, C13H9ClN2O5S, the N—H bond is trans to the C=O bond. The dihedral angle between the two aromatic rings is 85.4 (1)°. In the crystal, molecules are linked into zigzag C(4) chains along the b axis through N—H⋯O hydrogen bonds
N-(3-Nitrobenzoyl)benzenesulfonamide
In the title compound, C13H10N2O5S, the C=O bond in the —SO2—NH—CO— segment is anti to the meta-nitro group in the benzoyl ring, while the N—C bond has gauche torsions with respect to the S=O bonds. The molecule is twisted at the N atom with a dihedral angle of 79.9 (2)° between the sulfonyl benzene ring and the —SO2—NH—CO— segment. Furthermore, the dihedral angle between the benzeneline rings is 86.9 (2)°. In the structure, the molecules are linked into helical chains along the b axis via N—H⋯O hydrogen bonds
N-(3-Chlorobenzoyl)-2-methylbenzenesulfonamide
In the title compound, C14H12ClNO3S, the N—H bond in the C—SO2—NH—C(O) segment is anti to the C=O bond. Further, the C=O bond and the meta-Cl atom in the benzoyl ring are also anti to each other. The dihedral angle between the sulfonyl and the benzoyl benzene rings is 72.4 (1)°. In the crystal, molecules are linked by pairs of N—H⋯O hydrogen bonds, forming inversion dimers
N-(3-Chlorobenzoyl)-3-nitrobenzenesulfonamide
In the title compound, C13H9ClN2O5S, the dihedral angle between the two benzene rings is 83.5 (1)°. In the crystal, molecules are linked via N—H⋯O(S) hydrogen bonds into helical chains running along the b axis
2,2,2-Tribromo-N-(3-methylphenyl)acetamide
The asymmetric unit of the title compound, C9H8Br3NO, contains two independent molecules. The conformation of the N—H bond is anti to the 3-methyl substituent in the benzene ring in each molecule. The structure shows both intramolecular N—H⋯Br and intermolecular N—H⋯O hydrogen bonding, the latter leading to the formation of helical supramolecular chains along the b axis
2-Chloro-N-(4-chlorobenzoyl)benzenesulfonamide toluene hemisolvate
The unit cell of the title compound, C13H9Cl2NO3S·0.5C7H8, contains two molecules of 2-chloro-N-(4-chlorobenzoyl)benzenesulfonamide and one toluene molecule, which is disordered about a centre of inversion. The dihedral angle between the two aromatic rings is 85.7 (1)°. In the crystal, molecules are linked by pairs of N—H⋯O(S) hydrogen bonds, forming centrosymmetric dimers
