4-(5-Phenyl-3-trifluoromethyl-1<i>H</i>-pyrazol-1-yl)benzenesulfonamide

Significant twists between the aromatic rings are evident in the structure of the title compound, C(16)H(12)F(3)N(3)O(2)S. With reference to the pyrazole plane, the N- and C-bound benzene rings form dihedral angles of 57.12 (11) and 29.75 (11)°, respectively. The dihedral angle between the benzene rings is 52.82 (11)°. The presence of N-H⋯O(sulfonamide) and N-H⋯N(pyrazole) hydrogen bonds lead to supra-molecular tubes along the b-axis direction. These are connected into layers via C-H⋯O inter-actions involving a bifurcated O atom (not involved in the N-H⋯O hydrogen bonding). Layers stack along the a-axis direction.
