· For Sodium
Chloride, the anions
(Cl) have an fcc structure
with all of the octahedral
sites occupied by the cations (Na).
· Zinc
Sulfide has an fcc anionic structure and the cations use half of the tetrahedral sites.
· Zinc
Sulfide in the Wurtzite form has its anions in an
hcp array and the cations fill half of the tetrahedral sites.
· Aluminum
Oxide has the oxygen anions in an hcp array and the cations
use 2/3 of the octahedral
sites.
· Calcium
Fluoride has a simple cubic, sc, anion array with the cations filling
half of the body
centered,
cubic sites.
