Ce2Cu2Mg crystallizes in the tetragonal P4/mbm space group. Mg(1) is bonded to eight equivalent Ce(1) and four equivalent Cu(1) atoms to form a mixture of distorted corner and face-sharing MgCe8Cu4 cuboctahedra. Ce(1) is bonded in a 6-coordinate geometry to four equivalent Mg(1) and six equivalent Cu(1) atoms. Cu(1) is bonded in a 9-coordinate geometry to two equivalent Mg(1), six equivalent Ce(1), and one Cu(1) atom.
Ce2Cu2Mg crystallizes in the tetragonal P4/mbm space group. Mg(1) is bonded to eight equivalent Ce(1) and four equivalent Cu(1) atoms to form a mixture of distorted corner and face-sharing MgCe8Cu4 cuboctahedra. All Mg(1)-Ce(1) bond lengths are 3.42 Å. All Mg(1)-Cu(1) bond lengths are 3.07 Å. Ce(1) is bonded in a 6-coordinate geometry to four equivalent Mg(1) and six equivalent Cu(1) atoms. There are two shorter (2.92 Å) and four longer (2.98 Å) Ce(1)-Cu(1) bond lengths. Cu(1) is bonded in a 9-coordinate geometry to two equivalent Mg(1), six equivalent Ce(1), and one Cu(1) atom. The Cu(1)-Cu(1) bond length is 2.65 Å.
