Table . The standard deviation (SD), the minimum and maximum percentage of contribution of the Eelstat to the interaction energy, and the difference between %Eelstat max and %Eelstat min for the studied systems. We may set an arbitrary boundary between the ionic and covalent bonds, for instance, we can agree that an electrostatic contribution of less than 50% characterizes a covalent (polar covalent) bond while a contribution of more than 50% denotes an ionic bond (with polarized ions). The nature of the bonding in six species (Be2Te2, B2N2, B2P2, B2As2, In2N2, and Tl2N2) changes by changing the pathways to assess the energy components of EDA because the %Eelestat in these species changes from below 50% to more than 50%. The largest variation of %Eelestat is found for B2N2 (Δ%ΔEelestat = 28.8) that also shows the largest standard deviation (9.9) upon changing the pathways for EDA analysis. B2Sb2 has the second-largest variations in the standard deviation and electrostatic contribution in the interaction energy. However, this molecule remains within the arbitrary realm of covalent bonds as %Eelstat of the system changes from 20.1% to 48.4% that is within the limit of covalency.
