The value of z in ZnS type structure is 4

  • ZnS is found in two crystalline forms in the stoichiometric ratio of 1:1
  • The two forms are wurtzite and sphalerite.
  • They are polymorphs.
  • Wurtzite has a hexagonal structure while sphalerite has a cubic structure.
  • In both cases, Zinc and sulfide have tetrahedral coordination.
  • Sulphur occupies 8 corners and 6 faces = (8/8)+(6/2) = 4
  • Zn occupies 4 tetrahedral holes = (4/1) = 4
  • So the value of z in ZnS is 4
