Abstract:The molecule of the title compound, C12H7Cl4NO2S, is U-shaped, with the central C—S—N—C segment having a torsion angle of −58.7 (3)°. The dihedral angle between the benzene rings is 40.23 (2)°. Further, theorthoCl atom on the aniline ring issynto the N—H bond in the central –C—S(O2)—NH—C– segment. In the crystal, molecules are linked by pairs of N—H...O hydrogen bonds, forming inversion dimers that encloseR22(8) loops. These dimers are linked by C—H...O hydrogen bonds that form a doubleC(7) chain propagating a… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
