ZnS exists in two main crystalline forms. This dualism is an example of polymorphism. In each form, the coordination geometry at Zn and S is tetrahedral. The more stable cubic form is known also as zinc blende or sphalerite. The hexagonal form is known as the mineral wurtzite, although it also can be produced synthetically. The transition from the sphalerite form to the w… WebIf S 2-ions occupy the lattice points of a face-centered cubic unit cell and Zn 2+ ions are packed into every other tetrahedral hole, we get the unit cell of ZnS shown in the figure below. The structure of ZnS can therefore be described as follows. ZnS crystallizes in a cubic unit cell. The cell-edge length is 0.5411 nm.
