Structure similar to zinc blende is found in

Zinc blende (ZnS) has fcc structure and is an ionic crystal having 4 : 4 co-ordination number. In ZnS structure, sulphide ions occupy all FCC lattice points while Zn2+ ions are present in alternate tetrahedral voids. In zinc blend structure S-2 ions follows ccp/fcc arrangement,that means S-2 ions are present at corners and face centres .And half of alternate tetrahedral voids are occupied by Zn2+ions.CuCl has same structure as ZnS
