WebMadelung Constant = 2.408, but can vary somewhat according to details of structure. Example: Metal difluorides and dioxides, but not sulfides or other dihalides. Lattice seems to be appropriate for highly ionic cpds. … The Madelung constant is used in determining the electrostatic potential of a single ion in a crystal by approximating the ions by point charges. It is named after Erwin Madelung, a German physicist. Because the anions and cations in an ionic solid attract each other by virtue of their opposing charges, … See more The Madelung constant allows for the calculation of the electric potential Vi of all ions of the lattice felt by the ion at position ri where See more A fast converging formula for the Madelung constant of NaCl is See more The Madelung constant is also a useful quantity in describing the lattice energy of organic salts.
