Jj. Golding et al., WEAK INTERMOLECULAR INTERACTIONS IN SULFONAMIDE SALTS - STRUCTURE OF 1-ETHYL-2-METHYL-3 BENZYL IMIDAZOLIUM BIS[(TRIFLUOROMETHYL)SULFONYL]AMIDE, Chemical communications, (15), 1998, pp. 1593-1594
The crystal structure of a 1,2,3-trisubstituted imidazolium salt of th
e his [(trifluoromethyl)sulfonyl)] amide ion is presented; this salt i
s a prototype for similar, room temperature liquid, imidazolium salts;
the structure shows that the anion and cation interact weakly, with l
ittle if any hydrogen bonding present.
