Mg is alpha La structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded to six equivalent Mg(1) and six equivalent Mg(2) atoms to form a mixture of edge, corner, and face-sharing MgMg12 cuboctahedra. In the second Mg site, Mg(2) is bonded to six equivalent Mg(1) and six equivalent Mg(2) atoms to form a mixture of edge, corner, and face-sharing MgMg12 cuboctahedra.

In the first Mg site, Mg(1) is bonded to six equivalent Mg(1) and six equivalent Mg(2) atoms to form a mixture of edge, corner, and face-sharing MgMg12 cuboctahedra. All Mg(1)-Mg(1) bond lengths are 3.18 Å. All Mg(1)-Mg(2) bond lengths are 3.17 Å. In the second Mg site, Mg(2) is bonded to six equivalent Mg(1) and six equivalent Mg(2) atoms to form a mixture of edge, corner, and face-sharing MgMg12 cuboctahedra. All Mg(2)-Mg(2) bond lengths are 3.18 Å.
