title: N-(4-Chloro-phen-yl)-1,1,1-trifluoro-N-(trifluoro-methyl-sulfon-yl)methane-sulfonamide.
abstract: The title mol-ecule, also called 4-chloro-N,N-bis-(trifluoro-methane-sulfon-yl)aniline, C(8)H(4)ClF(6)NO(4)S(2), has non-crystallographic twofold symmetry with the pseudo-axis aligned along the Cl-C⋯C-N backbone of the mol-ecule: the SO(2)CF(3) residues lie to either side of the benzene ring. In the crystal, the presence of C-H⋯O contacts lead to the formation of a sequence of 12-membered {⋯HC(2)NSO}(2) synthons within a supra-molecular chain aligned along [101].
