In the theory of the cohesive energy of ionic or nearly ionic crystals, the electrostatic energy, or Madelung energy, is important. Generally, the electrostatic cohesive force persists, despite the presence of strong repulsive forces of ions of similar charge among the constituent ions. Because of the magnitude of the Madelung energy, it dominates the energy of formation of most ionic solids and therefore is of interest to chemists who are attempting to grow single crystals larger than microscopic powders. The amount of literature on the various methods of calculating the electrostatic energy of an ionic solid is absolutely overwhelming, but a methodical compilation of the results of these calculations does not seem to exist. Practically every textbook of physical chemistry or solid-state physics lists a number of references to original papers on this subject. Consequently, we list here only references pertinent to the problem at hand the calculation of the Madelung energy for Y2HfS5. The technique used here is elementary however, it seems not to be in any of the textbooks.
