ZnS has a ccp structure. S2- ions are present at the corners of the cube and centre of each face. Zn2+ ions occupy half of the tetrahedral sites. Each Zn2+ ion is surrounded by four S2- ions and each S2- ion is surrounded by four Zn2+ ions.

Q. In zinc blende structure,

zinc ions occupy half of the tetrahedral sites

each $Z n^{2 +}$ ion is surrounded by six sulphide ions

each $S^{2 -}$ ion is surrounded by six $Z n^{2 +}$ ions

it has fee structure

$Z n S$ has a $cc p$ structure. $S^{2 -}$ ions are present at the corners of the cube and centre of each face. $Z n^{2 +}$ ions occupy half of the tetrahedral sites. Each $Z n^{2 +}$ ion is surrounded by four $S^{2 -}$ ions and each $S^{2 -}$ ion is surrounded by four $Z n^{2 +}$ ions.
