Coordination number of Zn in ZnS is

Options

  1. A4
  2. B2
  3. C6
  4. DNone of these

Correct answer

A. 4

Step-by-step solution

In ZnS , S ⁻ ions adopt fcc lattice in which Zn ²⁺ ions are present at alternate tetrahedral sites. Hence, coordination number of S ²⁻ is equal to coordination number of Zn ²⁺ i.e. 4 .
