which is split into two parts. The first peak may be ascribed to the G3 molecules forming complexes with the lithium cations contributing all four oxygen atoms and, by doing so, enclosing the cations completely (see Figure ). Hence, the center-of-mass position of the surrounding G3 molecule approximately matches the position of the cation and the peak is found at a very close distance. The shoulder at 2 Å can also be ascribed to coordinating G3 molecules. However, the responsible G3 molecules in the first coordination sphere do not form complexes being as symmetric as the aforementioned ones and are therefore found at slightly larger distances from the center cation (see Figures and). This peak is more highly populated at low salt ratio mixtures as well as in the mixture with the highest salt content.
