In order to verify whether such products could be formed in our experiments on the graphite surface, we calculated optimized structures for adsorbed LinX clusters on the surface (see Table ), followed by calculations of the core level binding energies. The choice of these species was based on the previous report by Merinov et al. that in the presence of excess Li the anion F is three-or fourfold coordinated. Furthermore, a higher coordination of the anions, either fourfold (Li2O, Li2S, or LiCN ), sixfold (LiF ) or eightfold (Li3N ) coordination, is present also in the respective bulk structures. The resulting most stable structures are summarized in Table .
