Mg2Si is Cubic Laves structured and crystallizes in the cubic Fd-3m space group. Mg(1) is bonded to six equivalent Mg(1) and six equivalent Si(1) atoms to form a mixture of distorted corner, edge, and face-sharing MgMg6Si6 cuboctahedra. Si(1) is bonded in a 12-coordinate geometry to twelve equivalent Mg(1) atoms.
