What Is The Crystal Structure Of Magnesium Sulfide?

Magnesium sulfide has a rock salt crystal structure, which is a type of face-centered cubic lattice. In this structure, each magnesium ion is surrounded by six sulfide ions located at the corners of a regular octahedron, and each sulfide ion is surrounded by six magnesium ions located at the corners of a regular octahedron as well. The coordination number of both magnesium and sulfide ions is six, and the lattice constant (unit cell length) of magnesium sulfide is approximately 5.2 angstroms.
