The stability of several cubic molecular crystals is investigated on the basis of multipole interaction between the molecules. The stability of the cubic close-packed structure of heavy rare-gas crystals is due to the repulsion between electrical octapoles induced in atoms in the hexagonal close-packed structure. The face-centered cubic structures of carbon dioxide and cyclohexane-hexahalides and the body-centered cubic structures of silicon-tetrafluoride and hexamethylene-tetramine are configurations with the maximum electrostatic attraction between permanent charge distributions in the molecules. Pingpong balls containing two or four pieces of magnet represent these molecules with permanent multipoles; and it is demonstrated that a proper "crystal" of such balls (suspended in water) is stable.
