Symmetry Adapted Perturbation Theory (SAPT) analysis shows that stacking interactions of metal-chelate rings are stronger than stacking interactions of organic molecules due to much stronger electrostatic interactions caused by the presence of metals. Depending on the ligand, electrostatic component of chelate stacking can be stronger than dispersion component.
