Why frenkel defect is not observed in CsCl?

1.	Why frenkel defect is not observed in CsCl?
Answer» In Frenkel defects, the IONS leave their POSITIONS and OCCUPY interstitial sites. CsCl is does not show Frenkel defect because - -The ratio of radius between the two is not sufficient to allow the ions to occupy interstitial sites. -The coordination NUMBER of CS is high which LEADS to the strong force of attraction between the ions so they can not move from their space.
