MgDy2Cu2 crystallizes in the tetragonal P4/mbm space group. Mg(1) is bonded in a distorted square co-planar geometry to four equivalent Cu(1) atoms. Dy(1) is bonded in a 6-coordinate geometry to six equivalent Cu(1) atoms. Cu(1) is bonded in a 9-coordinate geometry to two equivalent Mg(1), six equivalent Dy(1), and one Cu(1) atom.
MgDy2Cu2 crystallizes in the tetragonal P4/mbm space group. Mg(1) is bonded in a distorted square co-planar geometry to four equivalent Cu(1) atoms. All Mg(1)-Cu(1) bond lengths are 3.01 Å. Dy(1) is bonded in a 6-coordinate geometry to six equivalent Cu(1) atoms. There are two shorter (2.88 Å) and four longer (2.90 Å) Dy(1)-Cu(1) bond lengths. Cu(1) is bonded in a 9-coordinate geometry to two equivalent Mg(1), six equivalent Dy(1), and one Cu(1) atom. The Cu(1)-Cu(1) bond length is 2.64 Å.
