Relationships between Lattice Energies and Surface Electrostatic Potentials and Areas of Anions

We show that the lattice energies of ammonium, sodium, and potassium salts can be expressed analytically in terms of the total charges of the anions and their computed surface electrostatic potentials and areas. The calculations have been carried out at the HF/6-31+G* level for 17 singly and doubly charged anions. Predicted lattice energies are presented for 10 compounds.
