What Is The Crystal Structure Of Solid Magnesium Chloride?

The crystal structure of solid magnesium chloride is a face-centered cubic lattice, also known as the rock salt structure. In this structure, each magnesium cation is surrounded by six chloride anions arranged at the vertices of an octahedron, and each chloride anion is surrounded by six magnesium cations arranged at the vertices of an octahedron. The coordination number of both cations and anions is 6. The lattice parameter for this crystal structure is approximately 5.2 Å.
