The material described by Mg2Zn crystallizes in the monoclinic C2/c space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded to seven Mg(1,1) and five equivalent Zn(1) atoms to form a mixture of distorted corner, edge, and face-sharing MgMg7Zn5 cuboctahedra. In the second Mg site, Mg(1) is bonded to seven Mg(1,1) and five equivalent Zn(1) atoms to form a mixture of distorted corner, edge, and face-sharing MgMg7Zn5 cuboctahedra. Zn(1) is bonded in a 10-coordinate geometry to ten Mg(1,1) atoms. is represented by the CIF file [CIF]
