The Structure of Zinc Blende. (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.

Formula AxXy, the coordination numbers (CNs) of A and X must be in the ratio of y:x. For rock salt and zinc blende, x = y and anions and cations have the same CN As we know cations are occupied in the voids and anions are present in the spheres. In zinc blende (ZnS), the sulphide ions are anions and are face centered. It 30 Apr 2017 The number of the closest neighbor atoms to a lattice point. 3 and the coordination number in the cubic Zinc Blende structure (ZnS).

Zinc blende structure coordination number

(i) pm pm This value lies between 0.225 and 0.414 hence a tetrahedral void is occupies coordination no. = 4 Which of the following statements is correct regarding the zinc blende type structure of an ionic compound? Options :- Coordination number of each cation and anion is two. It considers five tetrahedron configurations with the shape and size distortions characteristic of ternary zinc blende alloys, allows nonrandom distributions and, hence, site occupation preferences, conserves coordination numbers, respects stoichiometry, and assumes that next-neighbor values determine preferences beyond next-neighbor. ZnS, zinc sulfide (or zinc blende) forms an FCC unit cell with sulfide ions at the lattice points and much smaller zinc ions occupying half of the tetrahedral holes in the structure.

Structure that the coordination number is 8 for both ion types. Zinc blende structure Structure that the coordination number is 4; that is all ions are tetrehedrally coordinated.

However, zinc-blende differs from diamond in that it consists of ZincBlende structure is based on the FCC lattice and it is almost like the Zinc Blende (ZnS) Structure Coordination= 4, 4 Cation Coord. â€¹Copper has an 2 Jun 1986 VOLUME 56, NUMBER 22 While MnTe has the stable NiAs structure ~ith a direct band gap of l.30 eV and a Mn-Te bond length of 2.92 A, extrapolation of the data for the zinc-blende alloy Cdl „Mn„Teto x = 1 suggests.
