What Is The Crystal Structure Of Magnesium Sulphide?

Magnesium sulphide has a zincblende crystal structure, which is a common crystal structure for binary compounds of the form AB. In this structure, magnesium ions (Mg2+) occupy the tetrahedral sites while sulfide ions (S2-) occupy the octahedral sites. The lattice constant for magnesium sulphide in this crystal structure is approximately 5.67 Å.
