The Zincblende structure (also written "zinc blende") is named after the mineral zincblende , one form of zinc sulfide (β-ZnS). As in the rock-salt structure, the two atom types form two interpenetrating face-centered cubic lattices. Of course we see immediately that what many call Zinc blende or sphalerite is simply an fcc lattice with two atoms in the base: atom A at (0,0,0,) and atom B at (½, ½, ½). The lattice constant of cubic MnS with rock salt structure is 5.20 A, whilst the lattice constant of metastable cubic MnS with zinc blende structure is 5.60 ,~,, the latter being as dense as the wurtzite phase used in our experiments. Zincblende has a fcc Bravais lattice with two atoms in the basis. The conventional unit cell is a cube with sides of a.There are 4 S atoms (corners: 8 × ⅛ = 1, faces: 6 × ½ = 3) and 4 Zn atoms (interior) in the conventinal unit cell. The face-centered cubic system (cF) has lattice points on the faces of the cube, that each gives exactly one half contribution, in addition to the corner lattice points, giving a total of 4 lattice points per unit cell ( 1 ⁄ 8 × 8 from the corners plus 1 ⁄ 2 × 6 from the faces).

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.

In both structures, the cations occupy one of the two types of tetrahedral holes present. In either structure, the nearest neighbor connections are similar, but the distances and angles to further neighbors differs. The entire structure rests on three assumptions: (1) that equation (5) holds, (2) that the 100 per cent ionic zinc blende lattice is non-existent because C^ = C^, and (3) that the theory for polar lattices holds. The lattice constant of cubic MnS with rock salt structure is 5.20 A, whilst the lattice constant of metastable cubic MnS with zinc blende structure is 5.60 ,~,, the latter being as dense as the wurtzite phase used in our experiments.
