MgZn is Frank-Kasper $\mu$ Phase-like 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 in a 16-coordinate geometry to three equivalent Mg(2), four equivalent Mg(1), and nine equivalent Zn(1) atoms. In the second Mg site, Mg(2) is bonded in a 6-coordinate geometry to six equivalent Mg(1) and six equivalent Zn(1) atoms. Zn(1) is bonded to two equivalent Mg(2), six equivalent Mg(1), and four equivalent Zn(1) atoms to form a mixture of distorted corner, edge, and face-sharing ZnMg8Zn4 cuboctahedra.
MgZn is Frank-Kasper $\mu$ Phase-like 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 in a 16-coordinate geometry to three equivalent Mg(2), four equivalent Mg(1), and nine equivalent Zn(1) atoms. All Mg(1)-Mg(2) bond lengths are 3.08 Å. There are three shorter (3.25 Å) and one longer (3.26 Å) Mg(1)-Mg(1) bond length. There are six shorter (3.09 Å) and three longer (3.16 Å) Mg(1)-Zn(1) bond lengths. In the second Mg site, Mg(2) is bonded in a 6-coordinate geometry to six equivalent Mg(1) and six equivalent Zn(1) atoms. All Mg(2)-Zn(1) bond lengths are 2.71 Å. Zn(1) is bonded to two equivalent Mg(2), six equivalent Mg(1), and four equivalent Zn(1) atoms to form a mixture of distorted corner, edge, and face-sharing ZnMg8Zn4 cuboctahedra. There are two shorter (2.54 Å) and two longer (2.70 Å) Zn(1)-Zn(1) bond lengths.
