The material described by MgZn2 crystallizes in the monoclinic C2/m space group. Mg(1) is bonded to three equivalent Zn(1) and four equivalent Zn(2) atoms to form a mixture of distorted face and edge-sharing MgZn7 cuboctahedra. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 12-coordinate geometry to three equivalent Mg(1), four equivalent Zn(1), and five equivalent Zn(2) atoms. In the second Zn site, Zn(2) is bonded in a 12-coordinate geometry to four equivalent Mg(1), three equivalent Zn(2), and five equivalent Zn(1) atoms. is represented by the CIF card [CIF]
