The crystal structure described by MgYb2 crystallizes in the orthorhombic Cmcm space group. Mg(1) is bonded in a 10-coordinate geometry to ten equivalent Yb(1) atoms. Yb(1) is bonded to five equivalent Mg(1) and seven equivalent Yb(1) atoms to form a mixture of distorted corner, edge, and face-sharing YbYb7Mg5 cuboctahedra. is represented by the CIF file [CIF]
