MgAl2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. Mg(1) is bonded in a 16-coordinate geometry to four equivalent Mg(1), three equivalent Al(1), and nine equivalent Al(2) atoms. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded to six equivalent Mg(1) and six equivalent Al(2) atoms to form a mixture of edge, corner, and face-sharing AlMg6Al6 cuboctahedra. In the second Al site, Al(2) is bonded to six equivalent Mg(1), two equivalent Al(1), and four equivalent Al(2) atoms to form a mixture of edge, corner, and face-sharing AlMg6Al6 cuboctahedra.
MgAl2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. Mg(1) is bonded in a 16-coordinate geometry to four equivalent Mg(1), three equivalent Al(1), and nine equivalent Al(2) atoms. There is one shorter (3.20 Å) and three longer (3.32 Å) Mg(1)-Mg(1) bond lengths. All Mg(1)-Al(1) bond lengths are 3.19 Å. There are three shorter (3.09 Å) and six longer (3.16 Å) Mg(1)-Al(2) bond lengths. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded to six equivalent Mg(1) and six equivalent Al(2) atoms to form a mixture of edge, corner, and face-sharing AlMg6Al6 cuboctahedra. All Al(1)-Al(2) bond lengths are 2.69 Å. In the second Al site, Al(2) is bonded to six equivalent Mg(1), two equivalent Al(1), and four equivalent Al(2) atoms to form a mixture of edge, corner, and face-sharing AlMg6Al6 cuboctahedra. There are two shorter (2.64 Å) and two longer (2.80 Å) Al(2)-Al(2) bond lengths.
