The compound described by MgZn2 crystallizes in the monoclinic C2/c space group. Mg(1) is bonded to ten Zn(1,1,1) atoms to form a mixture of distorted corner, face, and edge-sharing MgZn10 cuboctahedra. There are three inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 12-coordinate geometry to five equivalent Mg(1) and seven Zn(1,1) atoms. In the second Zn site, Zn(1) is bonded in a 12-coordinate geometry to five equivalent Mg(1) and seven Zn(1,1,1) atoms. In the third Zn site, Zn(1) is bonded in a 12-coordinate geometry to five equivalent Mg(1) and seven Zn(1,1) atoms. is represented by the CIF card [CIF]
