The material structure described by MgDy2 crystallizes in the orthorhombic Cmcm space group. Mg(1) is bonded in a body-centered cubic geometry to two equivalent Dy(2) and six equivalent Dy(1) atoms. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 6-coordinate geometry to six equivalent Mg(1) and four equivalent Dy(2) atoms. In the second Dy site, Dy(2) is bonded to two equivalent Mg(1), four equivalent Dy(1), and six equivalent Dy(2) atoms to form a mixture of distorted edge, corner, and face-sharing DyDy10Mg2 cuboctahedra. is represented by the CIF file [CIF]
