Question

In zinc blende structure rzn*2 / rs-2​

Answer 1

Answer:

Zinc blende (ZnS) has fee structure. It is an ionic crystal having 4:4 coordination number. S2−S2− form fee lattice and Zn2+ has alternate tetrahedral voids. Hence, in zinc blende structure, the coordination number of cation (Zn2+) is 4.

Answer 2

Explanation:

The structure of Zinc Blende. Zinc Blende is the name given to the mineral ZnS. It has a cubic close packed (face centred) array of S and the Zn(II) sit in tetrahedral (1/2 occupied) sites in the lattice, giving a Unit Cell with 8 Zn and 16 S's. The display shows an idealised unit cell (Space group 216 F-43m).
