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 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

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

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
