Mg2Dy crystallizes in the hexagonal P6/mmm space group. Mg(1) is bonded in a 11-coordinate geometry to five equivalent Mg(1) and six equivalent Dy(1) atoms. Dy(1) is bonded in a 14-coordinate geometry to twelve equivalent Mg(1) and two equivalent Dy(1) atoms.
Mg2Dy crystallizes in the hexagonal P6/mmm space group. Mg(1) is bonded in a 11-coordinate geometry to five equivalent Mg(1) and six equivalent Dy(1) atoms. There are three shorter (3.01 Å) and two longer (3.26 Å) Mg(1)-Mg(1) bond lengths. All Mg(1)-Dy(1) bond lengths are 3.42 Å. Dy(1) is bonded in a 14-coordinate geometry to twelve equivalent Mg(1) and two equivalent Dy(1) atoms. Both Dy(1)-Dy(1) bond lengths are 3.26 Å.
