Weak intermolecular interactions in sulfonamide salts: structure of 1-ethyl-2-methyl-3-benzyl imidazolium bis[(trifluoromethyl)sulfonyl]amide

Abstract

The crystal structure of a 1,2,3-trisubstituted imidazolium salt of the bis[(trifluoromethyl)sulfonyl)]amide ion is presented; this salt is a prototype for similar, room temperature liquid, imidazolium salts; the structure shows that the anion and cation interact weakly, with little if any hydrogen bonding present.
