Some compounds with the zinc blende structure are listed in Table 1.9. The bonding is less ionic than in rock salt structure compounds. Thus, oxides do not usually have the zinc blende structure (ZnO, not included in Table 1.9, is an exception; it is dimorphic with zinc blende and wurtzite structure polymorphs).

This structure is a derivative of the diamond structure (see Fig. 9(b)) with each zinc atom surrounded by four sulfur atoms, and each sulfur atom surrounded by four zinc atoms in tetrahedral coordination.. The chalcopyrite minerals are derivatives of the sphalerite structure, with Cu 1998-09-01 structure of Zinc Blende. Zinc Blende - ZnS. Zinc Blende is the name given to the mineral ZnS. 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.

Browse 3D-printable models; View special Collections Chemical Structures Zincblende/sphalerite is based on a fcc lattice of anions whereas wurtzite is derived from an hcp array of anions. 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 third important structure for AB (binary) lattices is zinc blende (Figure 3D). It is based on the diamond structure, where every other atom is A or B. Many binary semiconductors have this structure, including those with one atom from the third (boron, aluminum, gallium [Ga], or indium [In]) and one from the fifth (nitrogen, phosphorus, arsenic [As], or antimony [Sb]) column of the periodic table (GaAs, InP, etc.).

The darker atoms signify a primitive cell (the smallest repeating structure that makes up a crystal). The orange, green, and purple planes represent the planes with Miller indices (100), (110), and (111), respectively. I made this because textbooks cannot rotate images.

Zinc sulfide (ZnS) crystallizes in two different forms: Wurtzite and Zincblende.

The zinc-blende structure: using some tetrahedral holes. Since there are two tetrahedral sites for every atom in a close-packed lattice, we can have binary compounds of 1:1 or 1:2 stoichiometry depending on whether half or all of the tetrahedral holes are occupied. Zinc-blende is the mineralogical name for zinc sulfide, ZnS.
