4-Chloro-N-(2,6-dimethylphenyl)benzenesulfonamide
In the title compound, C14H14ClNO2S, the amido H atom orients itself away from both the ortho-methyl groups in the adjacent aromatic ring. The molecule is twisted at the S atom with an C—SO2—NH—C torsion angle of −69.9 (2)°. The two aromatic rings are tilted relative to each other by 31.9 (1)°. In the crystal, the molecules are packed into zigzag chains along the b axis via intermolecular N—H⋯O hydrogen bonds
N-(2,4,6-Trichlorophenyl)maleamic acid
In the crystal structure of the title compound, C10H6Cl3NO3, the conformation of the amide bond is trans. The C=O and O—H bonds of the acid group are in the relatively rare anti position to each other. This is a consequence of the intramolecular O—H⋯O hydrogen bond donated to the amide carbonyl group stabilizing the molecular structure. In the crystal, intermolecular N—H⋯O hydrogen bonds link the molecules into zigzag chains along the c axis
N-(4-Methyl-2-nitrophenyl)succinamic acid
In the title compound, C11H12N2O5, the conformation of the N—H bond in the amide segment is syn to the ortho-nitro group in the benzene ring. The amide C=O and the carboxyl C=O of the acid segment are syn to each other and both are anti to the H atoms on the adjacent –CH2 groups. Furthermore, the C=O and O—H bonds of the acid group are in syn positions with respect to each other. The dihedral angle between the benzene ring and the amide group is 36.1 (1)°. The amide H atom shows bifurcated intramolecular hydrogen bonding with an O atom of the ortho-nitro group and an intermolecular hydrogen bond with the carbonyl O atom of another molecule. In the crystal, the N—H⋯O(C) hydrogen bonds generate a chain running along the [100] direction. Inversion dimers are formed via a pair of O—H⋯O(C) interactions, that form an eight-membered hydrogen-bonded ring involving the carboxyl group
2-Chloro-N-[(2-methylphenyl)sulfonyl]acetamide
In the title compound, C9H10ClNO3S, the amide H atom is syn with respect to the ortho-methyl group in the benzene ring and the C—S—N—C torsion angle is −66.9 (2)°. An intramolecular N—H⋯Cl hydrogen bond occurs. The crystal structure features inversion-related dimers linked by pairs of N—H⋯O hydrogen bonds
N-(3,4-Dichlorophenyl)-4-methylbenzenesulfonamide
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
N-(2-Chloro-4-methylphenyl)succinamic acid
In the title compound, C11H12ClNO3, the N—C=O fragment is twisted from the plane of the attached benzene ring by 48.39 (12)°. The carboxylic acid group is involved in O—H⋯O hydrogen bonding, which links pairs of molecules into centrosymmetric dimers. N—H⋯O hydrogen bonds link these dimers, related by translation along the a axis, into ribbons
4-Chloro-N-(3,5-dimethylphenyl)benzenesulfonamide
The asymmetric unit of the title compound, C14H14ClNO2S, contains two independent molecules, which are twisted at the S atoms with C—SO2—NH—C torsion angles of −69.4 (7)° and 66.0 (8)°. The sulfonyl and the anilino benzene rings are tilted relative to each other by 49.0 (4) and 61.7 (3)° in the two molecules. In the crystal, the molecules are linked into chains by N—H⋯O hydrogen bonds
Potassium N-bromo-2-methylbenzenesulfonamidate sesquihydrate
In the structure of the title compound, K+·C7H7BrNO2S−·1.5H2O, the K+ ion is heptacoordinated by three O atoms from water molecules and by four sulfonyl O atoms of N-bromo-2-methylbenzenesulfonamide anions. The S—N distance of 1.577 (5) Å is consistent with an S=N double bond. The crystal structure comprises sheets in the ac plane which are further stabilized by O—H⋯Br and O—H⋯N hydrogen bonds
N-(4-Methylphenylsulfonyl)succinamic acid
In the crystal structure of the title compound, C11H13NO5S, the amide C=O and the carboxyl C=O groups of the acid segment orient themselves away from each other. The dihedral angle between the benzene ring and the amide group is 69.0 (2)°. In the crystal, N—H⋯O and O—H⋯O hydrogen bonds link the molecules into layers parallel to the bc plane
2,2-Dimethyl-N-(2-methylphenylsulfonyl)propanamide
In the title compound, C12H17NO3S, the amide H atom is syn to the ortho-methyl group of the benzene ring and the C—S—N—C torsion angle is −65.39 (17)°. The crystal structure features inversion-related dimers linked by pairs of N—H⋯O hydrogen bonds in which the acceptor O atom is bound to the S atom
