Expert Answer:

Number of octahedral voids in ccp structure=n
Number of Tetrahedral voids in ccp structure=2n
n=Number of O-2 ions in packing
 
According space to space given space information comma
Number space of space straight X space per space unit space cell equals 1 third cross times n equals n over 3
Number space of space straight Y space per space unit space cell equals 1 third cross times 2 n equals fraction numerator 2 n over denominator 3 end fraction

Therefore comma space the space formula space of space the space compound
straight X subscript n divided by 3 space end subscript straight Y subscript 2 n divided by 3 end subscript space straight O
XY subscript 2 straight O subscript 3
