– 4:4 (tetrahedral)
S2- with Zn2+ in half Td holes
Polyhedra – vertex-sharing and
tetrahedra
Half of the tetrahedral holes in a cubic close packing are occupied.
The cubic ZnS structure.
(a) The sphalerite (zinc-blende) structure and (b) its projection representation. Note its relation to the ccp lattice , with half the tetrahedral holes occupied by Zn2+ ions.
