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, C8H4ClF6NO4S 2, has non-crystallographic twofold symmetry with the pseudo-axis aligned along the Cl - C⋯C - N backbone of the mol-ecule: the SO 2CF3 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 {⋯HC2NSO}2 synthons within a supra-molecular chain aligned along [101].
