在标题化合物 C16H12F3N3O2S 的结构中，芳环之间存在明显的扭曲。相对于吡唑平面，N-键合苯环和C-键合苯环分别形成57.12 (11)°和29.75 (11)°的二面角。苯环之间的二面角为52.82 (11)°。 N—H⋯O（磺酰胺）和N—H⋯N（吡唑）氢键的存在导致沿b轴方向的超分子管。它们通过涉及分叉 O 原子（不参与 N—H⋯O 氢键）的 C—H⋯O 相互作用连接成层。层沿a轴方向堆叠。
Significant twists between the aromatic rings are evident in the structure of the title compound, C16H12F3N3O2S. 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 supramolecular tubes along the b-axis direction. These are connected into layers via C—H⋯O interactions involving a bifurcated O atom (not involved in the N—H⋯O hydrogen bonding). Layers stack along the a-axis direction.
