In the title compound, C18H19N3O3S, the phenyl ring and the pyrazole ring are twisted with respect to each other by an angle of 49.11 (7)°. The C—N—S—C torsion angle is −122.5 (2)°. The methyl group bonded to the N atom of the pyrazole ring has a large deviation from the mean ring plane of 0.603 (3) Å. One intermolecular N—H...O and two non-classical intermolecular C—H...O hydrogen bonds are observed in the crystal structure.

In the title compound, [Zn(C17H14Cl2N3O3S)2(H2O)2], the ZnII ion has a tetrahedral coordination formed by the two N atoms of the sulfonamide groups and the two water molecules. Two inter- and two intramolecular O—H...O hydrogen bonds are observed in the crystal structure.
