Abstract

Solution studies of halide complexes of the transition metals, of general type [MXn]y− (X=Cl or Br), have been severely hampered by the existence of both solvation and solvolysis phenomena1. We demonstrate here that the use of room-temperature ionic liquids (often misleadingly referred to as molten salts) as solvents circumvents both of these problems, and permits the first reliable solution spectra to be recorded for these species; in some cases the spectra exhibit quite remarkable resolution.
