Substantial amounts of impurity, principally iron, are usually found in the composition of natural ZnS minerals that affect the physical and optical properties, preventing reproducible characterisation.

However, the lattice contains two different types of atoms. Each atom still has four covalent bonds, but these are bonds to atoms of the other type. This structure is referred to as the zinc-blende lattice, named after zinc-blende crystal (ZnS) as shown in Figure 2.2.6. Both the diamond lattice and the zinc-blende lattice are cubic lattices.

One important characteristic of a crystalline structure is its atomic packing factor. It has a cubic close packed (face centred) array of S and the Zn (II) sit in tetrahedral (1/2 occupied) sites in the lattice, giving a Unit Cell with 8 Zn and 16 S's. diamond cubic or Zinc blende structures.
