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)°, 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.

H atoms treated by a mixture of independent and constrained refinement max = 0.34 e Å3. 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. 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).
