4-Bromo-3-{N-[2-(3,4-dimethoxy­phen­yl)eth­yl]-N-methyl­sulfamo­yl}-5-methyl­benzoic acid monohydrate

In the title compound, C19H22BrNO6S·H2O, the dihedral angle between the planes of the two benzene rings is 3.1 (1)°. These rings are stacked over one another with their centroids separated by 3.769 (2) Å, indicating weak π–π inter­actions. In the crystal structure, mol­ecules are linked by O—H⋯O and O—H⋯(O,O) hydrogen bonds involving the water mol­ecule, forming a two-dimensional network parallel to (001)

N-(5-Bromo-2-chloro­benz­yl)-N-cyclo­propyl­naphthalene-2-sulfonamide

In the title compound, C20H17BrClNO2S, the dihedral angle between the benzene ring and the naphthalene plane is 8.95 (8)°. The crystal packing is stabilized by weak inter­molecular C—H⋯O, C—H⋯Cl and π–π [centroid–centroid distance = 3.8782 (16) Å] inter­actions

2,4-Dichloro-N-phenethyl­benzene­sulfonamide

In the title compound, C14H13Cl2NO2S, the dihedral angle between the phenyl ring and the benzene ring is 69.94 (9)°. Two short intra­molecular C—H⋯O contacts occur and a weak inter­molecular C—H⋯π inter­action is seen in the crystal
