ZnS – Zinc Blende, Sphalerite: Interactive 3D Structure. CONTROLS – 4:4 (tetrahedral) S 2-with Zn 2+ in half Td holes. Polyhedra – vertex-sharing and tetrahedra. Interactive model of this structure type at ChemTube3D.. The face-centred cubic (fcc) structure derives from the simple cubic type by adding an additional atom in the centres of all the faces of the cubic unit cell. Since faces are shared between two neighbouring cells, the total number of atoms in the unit cell is four. The coordination polyhedron is a cuboctahedron, i.e.

Since faces are shared between two neighbouring cells, the total number of atoms in the unit cell is four. The coordination polyhedron is a cuboctahedron, i.e. a cube whose corners Zinc selenide (ZnSe) is a light-yellow, solid compound comprising zinc (Zn) and selenium (Se). It is an intrinsic semiconductor with a band gap of about 2.70 eV at 25 °C (77 °F). ZnSe rarely occurs in nature, and is found in the mineral that was named after Hans Stille called " stilleite ." Crystal Structure of Zinc Blende. Zinc sulfide crystallizes in two different forms: wurtzite and zinc blende.

The radii of the two ions (Zn +2 = 74 pm and S-2 = 184 pm) led to the radius (r + / r –) as 0.40 which suggests a tetrahedral arrangement. S2! = 0.069 nm 0.184 nm = 0.375. The coordination number is four (Table 12.2), and the predicted crystal structure is zinc blende (Table 12.4). 12.8 The zinc blende crystal structure is one that may be generated from close-packed planes of anions.
