The structure described by MgZn2 is Bergman Structure: Mg32(Al,Zn)49 Bergman-derived structured and crystallizes in the orthorhombic Cmcm space group. Mg(1) is bonded to two equivalent Mg(1) and ten equivalent Zn(1) atoms to form a mixture of distorted face and edge-sharing MgMg2Zn10 cuboctahedra. Zn(1) is bonded in a 11-coordinate geometry to five equivalent Mg(1) and six equivalent Zn(1) atoms. is represented by the CIF file [CIF]
