The material structure described by Al2CuMg crystallizes in the orthorhombic Cmcm space group. Mg(1) is bonded in a 13-coordinate geometry to three equivalent Cu(1) and ten equivalent Al(1) atoms. Cu(1) is bonded in a 9-coordinate geometry to three equivalent Mg(1) and six equivalent Al(1) atoms. Al(1) is bonded in a 3-coordinate geometry to five equivalent Mg(1) and three equivalent Cu(1) atoms. is represented by the CIF card [CIF]
