What Is The Crystal Structure Of Magnesium Nitride?

Magnesium nitride has a crystal structure that belongs to the rock salt-type cubic system. In this crystal structure, each magnesium cation (Mg2+) is surrounded by six nitride anions (N3-) at the corners of a regular octahedron, while each nitride anion is coordinated to six magnesium cations at the corners of another octahedron. The Mg-N bond length in magnesium nitride is about 1.89 angstroms, and the lattice constant of the unit cell is approximately 4.21 angstroms.
