MgNd2Cu2 crystallizes in the tetragonal P4/mbm space group. Mg(1) is bonded to eight equivalent Nd(1) and four equivalent Cu(1) atoms to form a mixture of distorted corner and face-sharing MgNd8Cu4 cuboctahedra. Nd(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 Nd(1), and one Cu(1) atom.
