Corrugated Sheets

The molecule of the title compound, C16H16ClN3O3S·H2O, is L-shaped being bent at the S atom; the S—N—C—C torsion angle is 132.0 (3)°. The central part of the molecule, C—C—N—N=C, is almost linear, with the C—C—N—N and C—N—N=C torsion angles being −174.1 (2) and 176.0 (2)°, respectively. The dihedral angle between thep-toluenesulfonyl ring and the S—N—C—C(=O) segment is 67.5 (4)°, while that between the two aromatic rings is 52.17 (11)°. In the crystal, the water H atom is involved in O—H...O hydrogen bonds with a sulfonamide O atom and the carbonyl O atom. The water O atom is itself hydrogen bonded to both NH hydrogen atoms. These four hydrogen bonds lead to the formation of corrugated sheets lying parallel to (100). There are also weak C—H...O contacts present within the sheets.
