Hydrogen Bonding in Imidazolium Salts and its Implications for Ambient-temperature Halogenoaluminate(III) Ionic Liquids
The salts X (X = Br or I, emim = 1-ethyl-3-methylimidazolium) and have been prepared as solid-state models of the X-AlX3 (X = Cl or Br) ionic liquid systems.All three have been characterised crystallographically.The salts X (X = Br or I) are isomorphous and are composed of ions in an extended hydrogen-bonded network.The implications of these results for both the structure and solvent properties of the ionic liquids are discussed.
