Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536811051932
Abstract: In the title compound, C14H12ClNO3S·H2O, the dihedral angle between the sulfonyl and benzoyl benzene rings is 84.4 (2)°. In the crystal, every water molecule forms four hydrogen bonds with three different molecules of 4-chloro-N-(3-methylbenzoyl)benzenesulfonamide. One of the water H atoms forms a bifurcated hydrogen bond with both the sulfonyl and the carbonyl O atoms of the same molecule. Molecules are linked into layers in the ab plane through N—H...O and O—H...O hydrogen bonds.

Acta Crystallographica Section E , 2013, DOI: 10.1107/s1600536813002134
Abstract: In the title compound, C16H14ClN3O2S, the dihedral angle between the benzene and pyrazole rings is 52.75 (2)°, while that between the pyrazole and 4-chlorophenyl rings is 54.0 (3)°. The terminal sulfonamide group adopts an approximately tetrahedral geometry about the S atom with a C—S—N angle of 108.33 (10)°. In the crystal, pairs of N—H...N hydrogen bonds lead to the formation of inversion dimers. These dimers are linked via a second pair of N—H...N hydrogen bonds and C—H...O interactions, forming a two-dimensional network lying parallel to the bc plane. The two-dimensional networks are linked via C—H...Cl interactions, forming a three-dimensional structure.
