Coordination number of Zn in ZnS (Zine blende) is

1.	Coordination number of Zn in ZnS (Zine blende) is
Answer» 4 6 2 None of these Solution :In ZNS, `S^(2-)"ions ADOPT f.c.c. lattice in which " Zn^(2+)" ions are present in alternate tetrahedral sites "`. `THEREFORE" Co-ordination number of " S^(2-) = " Co-ordination number of " Zn^(2+) = 4`
