If the size difference between the ions is large or both the ions are not similar in size then sodium chloride structure is adopted by the lattice. ![]() This can be understood as, when the size difference between the ions is small or we can say both the ions are similar in size then cesium chloride structure is adopted by the crystal. The chemical formula of cesium chloride is \ is due to size difference between the ions. The length of the side of the unit cell is 412 pm and. On heating, crystal with cesium chloride type of crystal lattice changes to sodium chloride type of lattice. In CsCl structure, caesium and chloride ions are in contact along the body diagonal of the unit cell. The space group of the caesium chloride (CsCl) structure is called Pm 3 m (in HermannMauguin notation), or '221' (in the International Tables for Crystallography). Hint:Coordination number of metal in cesium chloride is 8 and in sodium chloride type of ionic crystal, coordination number of metal is 6. ![]()
