4-[5-(Furan-2-yl)-3-trifluoromethyl-1H-pyrazol-1-yl]benzenesulfonamide

Abstract

In the title compound, C14H10F3N3O3S, there are significant twists in the molecule, 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—Car—Car(ar = aromatic) torsion angle = 83.70 (19)°]. One amino H atom forms a hydrogen bond to the tricoordinate pyrazole N atom and the other interacts with a sulfonamide O atom, forming a supramolecular chain along [010]. The chains are consolidated into a supramolecular layersviaC—H...O interactions 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.
