In the Zinc Blende structure, the ions are arranged in CCP(Cubic Close Packing) manner. In the CCP arrangement, there are 8 tetrahedral voids and 4 octahedral voids present.The S2- ions are present in FCC (Face Centered Cubic) arrangement. i.e. The S2-ions are present at the corner of the cube and at the centre of each face.The Zn2+ ions are present in the alternative tetrahedral void. Each Zn2+ ion is surrounded tetrahedrally by four S2-ions and each S2- ion is surrounded tetrahedrally by four Zn2+ions. Thus, the structure has 4:4 coordination.

Detailed Solution

In the Zinc Blende structure, the ions are arranged in CCP(Cubic Close Packing) manner. In the CCP arrangement, there are 8 tetrahedral voids and 4 octahedral voids present.
The $S^{2 -}$ ions are present in FCC (Face Centered Cubic) arrangement. i.e. The $S^{2 -}$ ions are present at the corner of the cube and at the centre of each face.
The ${Zn}^{2 +}$ ions are present in the alternative tetrahedral void.
Each ${Zn}^{2 +}$ ion is surrounded tetrahedrally by four $S^{2 -}$ ions and each $S^{2 -}$ ion is surrounded tetrahedrally by four ${Zn}^{2 +}$ ions.
Thus, the structure has 4:4 coordination.
