Radius Ratio | Octahedral and Tetrahedral Voids

A : The number of spheres are equal to the number of octahedral voids as well as tetrahedral void. R : Octahedral void and tetrahedral void has equal size.

In a compound XY_(2) O_(4) , oxide ions are arranged in CCP and cations X are present in octahedral voids. Cations Y are equally distributed between octahedral and tetrahedral voids. The fraction of the octahedral voids occupied is :-

In a crystal structure oxide ion forms CCP . A^(2+) ion occupy one of the octahedral voids and B^(3+) ions are equally distributed between tetrahedral and octahedral voids.If (1)/(8) th of the tetrahedral voids are occupied by B^(3+) ion and sum of % occupancy of B^(3+) ion in octahedral and tetrahedral voids is (x)/(2) then the value of x is

In a crystalline solid anions B are arranged in cubic close packing. Cation A are equally distributed between octahedral and tetrahedral voids. If all the octahedral voids are occupied, the formula for the solid is

In a crystalline solid, anions B are arranged in a ccp. Cations A are equally distributed between octahedral and tetrahedral voids. If all the octahedral voids are occupied, the formula of the compound is A_2B//A_3B .

In a crystalline solid, anions B are arranged in ccp structure. Cations A are equally distributed between octahedral and tetrahedral voids if all the octahedral voids are occupied the formula of the ionic solids will be
