Each complex is dissected into its closed-shell ionic components via nine different pathways as it is represented in Orbital interaction energy, Eoi, is often associated with covalency within the framework of EDA. We start by examining the sensitivity of EDA in defining the nature of bonds to the selected pathway by measuring the contribution of Eoi in beryllium chalcogenides. The interaction of the hard Be 2+ ion with large and polarizable anions increases the relative contribution of the Eoi in the total interaction energy as expected. However, as it is represented in Figure , different pathways suggest various rates in the covalent character growth as the atomic numbers of the chalcogens increase. Interestingly, while in the case of Be2O2 pathways 2 to 5 predict nearly the same percentage of the Eoi contribution in the interaction energy (23.3% to 23.9%) the same pathways predict significantly different covalent characters for heavier chalcogenides. Notably, the contribution of Eoi in the Be-Te bond shows a significant oscillation varying between 43.4% to 62.6% of the total interaction energy. The variation of the covalent character in boron pnictogenides is even more dramatic. In particular, while pathway 3 predicts that the covalency of B-Se is far more considerable than that of B-N bond, pathways 8 and 9 suggest that the covalency of B-N and B-Se are comparable and B-N is even more covalent than B-P and B-As bonds. To further investigate the varying extent of the ionicity/covalency among M2X2 systems, the standard deviation of the percentage of electrostatic interaction energy, Eelstat, obtained from different pathways for each species is computed and listed in Table along with the minimum, maximum, and the difference between the extremum values of the %Eelstat. The standard deviation and the difference between the minimum and maximum of the electrostatic contribution, %Eelstat, obtained from different pathways are two key parameters that reflect the path-dependency of EDA energy components. The largest standard deviations are found for B2N2 (9.9), B2Sb2 (9.4), and B2P2 (8.7), respectively. The Δ%Eelstat for 15 species are found to be more than 15% and that of 9 species are between 10-15%. The largest variation of the contribution of %Eelstat and highest standard deviations belongs to semimetals, systems with bonds that are indeed the borderline between ionic and covalent character.
