Halogenated compounds are gaining importance in medicinal chemistry and materials science. The multipolar contribution of anisotropic molecular mechanics potentials can reproduce the in- and out-of plane angular dependencies of the Coulomb contribution from quantum chemistry energy decomposition analyses, accounting for the impact of the “sigma hole” on the interaction energies without resorting to extraneous, fictitious, off-centered, partial atomic charges.
