What would be the structure of the crystal if rc/ra=1? hexagonal closed packed or anything else?
What would be the structure of the crystal if rc/ra< .23 ? What would be the structure of the crystal if rc/ra>1 ?

PS: rc=radius of cation
ra=radius of anion And I am not talking about crystal lattice... That is cubic here I think... I am talking about co ordination of the crystal molecules,atoms,ions...
