The salts [emim]X (X = Br or I, emim = 1-ethyl-3-methylimidazolium) and [emim][AlBr4-] have been prepared as solid-state models of the [emim]X-AlX(3) (X = Cl or Br) ionic liquid systems. All three have been characterised crystallographically. The salts [emim]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.
