N,N′-Bis(4-chlorophenyl)maleamide
In the crystal of the title compound, C16H12Cl2N2O2, the two C=O groups are anti to each other, while one of them is syn and the other is anti to their adjacent C—H bonds. The two benzene rings are oriented at an interplanar angle of 56.4 (1)°, while the dihedral angles between the central amide group (N–C–C–C–C–N) and these rings are 3.6 (1) and 54.1 (1)°. An intramolecular N—H⋯O hydrogen bond occurs. In the crystal, intermolecular N—H⋯O hydrogen bonds link the molecules into infinite chains along the a axis
4-Chloro-N-(2-chlorophenyl)benzenesulfonamide
In the crystal structure of the title compound, C12H9Cl2NO2S, the N—C bond in the C—SO2—NH—C segment has gauche torsions with respect to the S=O bonds. The molecule is twisted at the S atom with an C—SO2—NH—C torsion angle of 57.6 (3)°. The N—H bond is syn to the ortho-chloro group in the anilino benzene ring. The two benzene rings are tilted relative to each other by 84.7 (1)°. The crystal structure features inversion dimers linked by N—H⋯O(S) hydrogen bonds. An intramolecular N—H⋯Cl hydrogen bond is also observed
Sodium N-bromo-2-chlorobenzenesulfonamidate sesquihydrate

3,5-Dichlorophenyl 4-methylbenzoate
The structure of the title compound, C14H10Cl2O2, resembles those of 3-chlorophenyl 4-methylbenzoate, 2,6-dichlorophenyl 4-methylbenzoate and 2,4-dichlorophenyl 4-methylbenzoate, with similar bond parameters. The dihedral angle between the benzene and benzoyl rings is 48.81 (6)°
Potassium N,4-dichlorobenzenesulfonamidate monohydrate
The structure of the title salt hydrate, K+·C6H4Cl2NO2S−·H2O, shows each of the sulfonyl O and water O atoms to be bidentate bridging.
