Coordination number $(4:4)$; $ccp$; $Zn^{2+}$ ion in the alternate tetrahedral voids

(A) $ZnS$ (Zinc blende) has a cubic close packed $(ccp)$ structure where $S^{2-}$ ions form the lattice.$Zn^{2+}$ ions occupy half of the available tetrahedral voids.In this structure,each $Zn^{2+}$ ion is tetrahedrally surrounded by four $S^{2-}$ ions,and each $S^{2-}$ ion is tetrahedrally surrounded by four $Zn^{2+}$ ions,resulting in a coordination number of $(4:4)$.
