The structure described by MgZn is Bergman Structure: Mg32(Al,Zn)49 Bergman-derived structured and crystallizes in the monoclinic C2 space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 12-coordinate geometry to two equivalent Mg(2), three equivalent Mg(1), three equivalent Zn(1), and four equivalent Zn(2) atoms. In the second Mg site, Mg(2) is bonded to four equivalent Mg(1), two equivalent Zn(1), and six equivalent Zn(2) atoms to form distorted MgMg4Zn8 cuboctahedra that share corners with six equivalent Mg(2)Mg4Zn8 cuboctahedra, edges with four equivalent Zn(1)Mg8Zn4 cuboctahedra, edges with six equivalent Mg(2)Mg4Zn8 cuboctahedra, and faces with four equivalent Zn(1)Mg8Zn4 cuboctahedra. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to two equivalent Mg(2), six equivalent Mg(1), and four equivalent Zn(2) atoms to form distorted ZnMg8Zn4 cuboctahedra that share corners with six equivalent Zn(1)Mg8Zn4 cuboctahedra, edges with four equivalent Mg(2)Mg4Zn8 cuboctahedra, edges with six equivalent Zn(1)Mg8Zn4 cuboctahedra, and faces with four equivalent Mg(2)Mg4Zn8 cuboctahedra. In the second Zn site, Zn(2) is bonded in a 11-coordinate geometry to three equivalent Mg(2), four equivalent Mg(1), two equivalent Zn(1), and two equivalent Zn(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
