At low salt content up to x([Li][NTf 2 ]) = 1/3, each lithium cation is on average surrounded by two G3 molecules, coordinating [Li] + by on average two to three oxygen atoms each. This results in total coordination numbers of 4.3 to 4.5 at all temperatures. Besides, these mixtures are characterized by high numbers of free G3 molecules and, on average, long end-to-end distances of the G3 molecules. Consequently, these mixtures should be considered concentrated solutions rather than SILs.
