4-(3,4-Diacetyl-5-methyl-1H-pyrazol-1-yl)benzene-sulfonamide.

ABSTRACT: In the title mol-ecule, C(14)H(15)N(3)O(4)S, the pyrazole ring is aligned at a dihedral angle of 55.5?(1)° with respect to the benzene ring; the mean planes of the acetyl substituents are twisted by 13.4?(3) and 30.1?(3)° with respect to the pyrazole ring. Inter-molecular classical N-H?O and weak C-H?O hydrogen bonding links the mol-ecules, forming a three-dimensional network architecture in the crystal structure.

4-[5-(Furan-2-yl)-3-trifluoro-methyl-1H-pyrazol-1-yl]benzene-sulfonamide.

Project description: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.
