The crystal structure described by LaCuMg crystallizes in the hexagonal P-62m space group. Mg(1) is bonded in a 4-coordinate geometry to six equivalent La(1), two equivalent Cu(1), and two equivalent Cu(2) atoms. La(1) is bonded in a 11-coordinate geometry to six equivalent Mg(1), one Cu(2), and four equivalent Cu(1) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(2) is bonded in a 9-coordinate geometry to six equivalent Mg(1) and three equivalent La(1) atoms. In the second Cu site, Cu(1) is bonded in a 9-coordinate geometry to three equivalent Mg(1) and six equivalent La(1) atoms. is represented by the CIF file [CIF]
