For mole fractions greater than 0.5, the coordinating G3 molecules are increasingly replaced by [NTf 2 ] -, leading to the formation of stable Li bridges between adjacent [NTf 2 ] -anions. For these mixtures, the mobility of the system is found to be drastically decreased. Moreover, the mixtures only barely exhibit liquid-like dynamical properties and do not tend to form many stable complexes between [Li] + and G3. Hence, these mixtures also cannot be characterised as SILs.
