4-(3-Chloro-2,2-dimethyl­propanamido)­benzene­sulfonamide

In the title compound, C₁₁H₁₅ClN₂O₃S, the 3-chloro-2,2-dimethyl­propanamide and sulfonamide substituents are arranged on opposite sides of the benzene ring plane. In the crystal, mol­ecules are linked by N—H...O and C—H...O hydrogen bonds, forming a three-dimensional network.

4-(5-Chloro­penta­namido)­benzene­sulfonamide

The mol­ecular conformation of the title compound, C₁₁H₁₅ClN₂O₃S, is stabilized by a C—H...O hydrogen bond, forming an S(6) ring motif. In the crystal, mol­ecules are linked by two pairs of inversion-related N—H...O hydrogen bonds, generating R₂²(8) and R₂²(20) ring motifs, resulting in chains running along [0-11]. These chains are connected by N—H...O hydrogen bonds along [100], forming layers parallel to (011). There are also C—H...π inter­actions between the layers, which consolidate the three-dimensional structure.

4-[3-(4-Methyl­piperidin-1-yl)propan­amido]­benzene­sulfonamide monohydrate

In the title compound, C₁₅H₂₃N₃O₃S·H₂O, the piperidine ring has a chair conformation. In the crystal, the sulfonamide mol­ecules are linked by N—H...O hydrogen bonds, forming a layer parallel to (10-1). The layers are inter­connected via N—H...O_w, O_w—H...N and O_w—H...O (w = water) hydrogen bonds, forming a three-dimensional network.
