Answer» A compound with formula $A B_{2} O_{4}$ adopts a crystal structure in which $O^{2 -}$ ions forms ccp arrangement. $A^{2 +}$ ions occupy octahedral voids while $B^{3 +}$ ions are distributed equally between tetrahedral and octahedral voids. The fraction of octahedral and tetrahedral voids occupied respectively are:
