Sphalerite

The mineral crystallizes in the cubic crystal the crystal structure, zinc and sulfur atoms are tetrahedrally coordinated. The structure is closely related to the structure of hexagonal analog is known as the wurtzite structure. The lattice constant for zinc sulfide in the zinc blende crystal structure is nm, calculated from geometry and ionic radii of nm .
