Question

The number of octahedral voids in a unit cell of Sphalerite (ZnS) structure is

Answer 1

Zincblende/sphalerite is based on a fcc lattice of anions whereas wurtzite is derived from an hcp array of anions. In both structures, the cations occupy one of the two types of tetrahedral holes present

Answer 2

The answer to the question is that the number of octahedral voids per atom is one, they are as same as ccp structure.

So here is your answer
