4-Bromo-N-(4-bromophenyl)benzenesulfonamide

Abstract

The molecule of the title compound, C12H9Br2NO2S, is U shaped with the central C—S—N—C segment having a torsion angle of 63.2 (4)°. Further, the dihedral angle between the benzene rings is 38.5 (2)°. The crystal structure features strong N—H...O hydrogen bonds that form infinite [100]C(4) chains. Molecules in adjacent chains are interlinkedviaC—H...O interactions which run along thebaxis, formingC(7) chains. This results in a two-dimensional network in theabplane; adjacent networks are connected by short Br...Br contacts [3.5092 (8) Å] propagating along the diagonal of theacplane, so that a three-dimensional supramolecular architecture ensues.

“…The dihedral angle between the planes of the two data reports benzene rings is 41.17 (19) . In comparison, the dihedral angles between the planes of the two benzene rings in the reported structures of 4-bromo-N-(4-bromophenyl)benzenesulfonamide, (II) (Rodrigues et al, 2015), and 4-bromo-N-(4nitrophenyl)benzenesulfonamide, (III) (Rodrigues et al, 2016), are slightly less than that in (I), with values of 38.5 (2) in (II) and 32.6 (6) in (III).…”

“…In recent years, extensive research studies have been carried out on the synthesis and evaluation of the pharmacological activities of molecules containing a sulfonamide moiety, and important pharmacophores have been reported (Mohan et al, 2013). With this in mind and in our continued efforts for understanding the structures of N-(4-substituted phenyl)-4bromobenzenesulfonamides (Rodrigues et al, 2015(Rodrigues et al, , 2016, we report herein the crystal structure of 4-bromo-N-(4-fluorophenyl)benzenesulfonamide, (I).…”
