4-[5-(4-Chloro-phen-yl)-3-methyl-1H-pyrazol-1-yl]benzene-sulfonamide.

ABSTRACT: In the title compound, C(16)H(14)ClN(3)O(2)S, the dihedral angle between the benzene and pyrazole rings is 52.75?(2)°, while that between the pyrazole and 4-chloro-phenyl rings is 54.0?(3)°. The terminal sulfonamide group adopts an approximately tetra-hedral geometry about the S atom with a C-S-N angle of 108.33?(10)°. In the crystal, pairs of N-H?N hydrogen bonds lead to the formation of inversion dimers. These dimers are linked via a second pair of N-H?N hydrogen bonds and C-H?O interactions, forming a two-dimensional network lying parallel to the bc plane. The two-dimensional networks are linked via C-H?Cl interactions, forming a three-dimensional structure.

Crystal structures of isomeric 3,5-di-chloro-N-(2,3-di-methyl-phen-yl)benzene-sulfonamide, 3,5-di-chloro-N-(2,6-di-methyl-phen-yl)benzene-sulfonamide and 3,5-di-chloro-N-(3,5-di-methyl-phen-yl)benzene-sulfonamide.

Project description:The crystal structures of three isomeric compounds of formula C14H13Cl2NO2S, namely 3,5-di-chloro-N-(2,3-di-methyl-phen-yl)-benzene-sulfonamide (I), 3,5-di-chloro-N-(2,6-di-methyl-phen-yl)benzene-sulfonamide (II) and 3,5-di-chloro-N-(3,5-di-methyl-phen-yl)benzene-sulfonamide (III) are described. The mol-ecules of all the three compounds are U-shaped with the two aromatic rings inclined at 41.3?(6)° in (I), 42.1?(2)° in (II) and 54.4?(3)° in (III). The mol-ecular conformation of (II) is stabilized by intra-molecular C-H?O hydrogen bonds and C-H?? inter-actions. The crystal structure of (I) features N-H?O hydrogen-bonded R22(8) loops inter-connected via C(7) chains of C-H?O inter-actions, forming a three-dimensional architecture. The structure also features ?-? inter-actions [Cg?Cg = 3.6970?(14)?Å]. In (II), N-H?O hydrogen-bonded R22(8) loops are inter-connected via ?-? inter-actions [inter-centroid distance = 3.606?(3)?Å] to form a one-dimensional architecture running parallel to the a axis. In (III), adjacent C(4) chains of N-H?O hydrogen-bonded mol-ecules running parallel to [010] are connected via C-H?? inter-actions, forming sheets parallel to the ab plane. Neighbouring sheets are linked via offset ?-? inter-actions [inter-centroid distance = 3.8303?(16)?Å] to form a three-dimensional architecture.

4-Chloro-N-(2-chloro-phen-yl)-2-methyl-benzene-sulfonamide.

Project description:In the crystal structure of the title compound, C(13)H(11)Cl(2)NO(2)S, the conformations of the N-C bond in the C-SO(2)-NH-C segment are trans and gauche with respect to the S=O bonds.

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.
