چکیده
In the title compound, C(14)H(10)F(3)N(3)O(3)S, there are significant twists in the mol-ecule, as seen in the values of the dihedral angles between the pyrazole ring and each of the furan [31.1 (2)°] and benzene rings [55.58 (10)°]. The amino N atom occupies a position almost normal to the benzene ring [N-S-C(ar)-C(ar) (ar = aromatic) torsion angle = 83.70 (19)°]. One amino H atom forms a hydrogen bond to the tricoordinate pyrazole N atom and the other inter-acts with a sulfonamide O atom, forming a supra-molecular chain along [010]. The chains are consolidated into a supra-molecular layers via C-H⋯O inter-actions involving the second sulfonamide O atom; layers stack along [10-1]. The furan ring was found to be disordered over two diagonally opposite orientations of equal occupancy.
