Options :- Coordination number of each cation and anion is two. It considers five tetrahedron configurations with the shape and size distortions characteristic of ternary zinc blende alloys, allows nonrandom distributions and, hence, site occupation preferences, conserves coordination numbers, respects stoichiometry, and assumes that next-neighbor values determine preferences beyond next-neighbor. ZnS, zinc sulfide (or zinc blende) forms an FCC unit cell with sulfide ions at the lattice points and much smaller zinc ions occupying half of the tetrahedral holes in the structure. A calcium fluoride unit cell, like that shown in Figure 17 , is also an FCC unit cell, but in this case, the cations are located on the lattice points; equivalent calcium ions are located on the lattice points of In sphalerite the sulfur atoms are in a cubic close-packed array, with half of the tetrahedral sites occupied. This structure is a derivative of the diamond structure (see Fig. 9(b)) with each zinc atom surrounded by four sulfur atoms, and each sulfur atom surrounded by four zinc atoms in tetrahedral coordination.

Zinc Blende [(Zn,Fe)S] Structure. Zinc blende, also known as sphalerite, is an important ore from which zinc metal is obtained. It consists largely of zinc sulfide in crystalline form but almost always contains variable iron.

Correct Answer: 4. Explanation: No explanation available.
You can also look at this structure as a hexagonal closest packed lattice of sulfur ions with half the tetrahedral holes filled with zinc The zinc blende structure results in a coordination number of 4 for each Zn 2+ ion and a tetrahedral arrangement of the four S 2− ions around each Zn 2+ ion. Formula AxXy, the coordination numbers (CNs) of A and X must be in the ratio of y:x. For rock salt and zinc blende, x = y and anions and cations have the same CN As we know cations are occupied in the voids and anions are present in the spheres. In zinc blende (ZnS), the sulphide ions are anions and are face centered.
