Which of the following statement(s) is/are correct with respect to zinc blende structure? — Solid State Chemistry Question

💡 Solution & Explanation

In ZnS, $S_2$- ions form the FCC lattice (and are thus at the corners and face centers). Zn2+ ions occupy alternate tetrahedral voids. The coordination numbers are 4:4, and there are Z = 4 ZnS formula units per unit cell.
