Abstract

Neutron diffraction with isotopic substitution has been applied to examine the potential for complex-ion formation in protic imidazolium bis{(trifluoromethyl)sulfonyl}imide ionic liquids. Strong cation–anion hydrogen-bonding in the 1:1 base:acid ionic liquid results in a high population of anions adopting a cis-conformation and, on adding excess imidazole (2:1 base:acid stoichiometry), cation–base and base–base correlations were identified however, persistent hydrogen-bond associations were not observed.
