Lattice Energies for Groups 1 and 2 Halides from Absolute Hardness
Abstract
In this work, we presented new empirical equations to calculate the lattice energy values of groups 1 and 2 halides based on absolute hardness values of cations and anions forming the ionic compound.
In
the given equations, r+ and r+2 = cation radius (pm); η+
and η+2 = cation absolute hardness (eV) and η- = anion
absolute hardness (eV). Here, it should be noted that calculated lattice energy
values for mentioned ionic compounds are in good agreement with the reference
values obtained from the literature.
