Abstract
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)degrees, respectively. The dihedral angle between the benzene rings is 52.82 (11)degrees. The presence of N-H center dot center dot center dot O(sulfonamide) and N-H center dot center dot center dot N(pyrazole) hydrogen bonds lead to supramolecular tubes along the b-axis direction. These are connected into layers via C-H center dot center dot center dot O interactions involving a bifurcated O atom (not involved in the N-H center dot center dot center dot O hydrogen bonding). Layers stack along the a-axis direction.
