Zinc Sulphide Moleculor Structure Model

Model : 55X-ZnS

DESCRIPTION-
ZnS has a unique structure type compared to other molecules, having different types of unique structures. ZnS can have a zinc blende structure, which is a "diamond-type network", and at a different temperature, ZnS has a hexagonal type symmetry. Structure-wise, the zinc blende structure is more thermodynamically favored. Zinc blende is a compound that comes in two forms: sphalerite and wurtzite. These are characterized by a 1:1 ratio of zinc to sulfur and maintain a tetrahedral arrangement in both forms. 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 differ. Zincblende has 4 asymmetric units in its unit cell, whereas wurtzite has 2. Unlike wurtzite, zincblende is its own antitype—you can switch the anion and cation positions in the cell and it doesn't matter (as in NaCl). In fact, replacement of both the Zn and S with C gives the diamond structure, making this structure useful for representation in a chemistry molecular model.
