The splitting of the dependencies is mainly due to the orbital type of the ion involved in the complex formation. For example, the dependence of the energy of solvent binding to anions on the ε HOMO parameter (Figure E, Figure ) is split into two curves: one consisting of OH -, F -, BF 4 -, and PF 6 -and the second one comprised of the other ions. The MO analysis shows (Table .1) that the ions from the first dependence possess multiple HOMOs of the same energy. A similar division into two dependencies can be seen in z 0 (ε HOMO ), for example, for the complexes with DMC (Figure , TfO -, TFSI -, and halides. There is a similar trend for the adsorption on electrodes (Figure ) and for complexation with water (Figure H), while it is not observed for DMC (Figure ). Theoretical evaluations can shed light on the nature of such dependencies by establishing the distance between the ion and the electrode or solvent molecule at which the total energy of the system would be minimized. Taking into account the available data, we can assume that the division is caused by the specific composition of the LUMO orbital and does not depend on the number of LUMO orbitals with the same energy. Taking into account the data on DMC, it is quite natural to conclude that the molecular orbitals of the solvent molecule influence the complex formation.
