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-HN hydrogen bonds lead to the formation of inversion dimers. These dimers are linked via a second pair of N-HN hydrogen bonds and C-HO interactions, forming a two-dimensional network lying parallel to the bc plane. The two-dimensional networks are linked via C-HCl interactions, forming a three-dimensional structure.
