The structure described by La2Cu2Mg crystallizes in the tetragonal P4/mbm space group. Mg(1) is bonded to eight equivalent La(1) and four equivalent Cu(1) atoms to form a mixture of distorted face and corner-sharing MgLa8Cu4 cuboctahedra. La(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 La(1), and one Cu(1) atom. is represented by the CIF file [CIF]
