The Zinc Blende or Sphalerite Structure.

Zinc blende is same to diamond cubic structure, but the two FCC sub-lattices are occupied by atoms of two dissimilar elements. Some of the significant compounds which possess this structure are semiconductors like InSb, GaAs and also ZnS and CuCl. Zinc sufide in diamond structure is generally known as Zinc Blende . 2 samples of zinc blende ores are shown below. Its color is usually yellow, brown, or gray to gray-black, and it may be shiny or dull. Iron content in the ore makes it opaque/black. It is also known as the miner's blackjack or mock lead.
