The crystal structure described by LaCu2Mg crystallizes in the hexagonal P6_3/mmc space group. Mg(1) is bonded in a distorted hexagonal planar geometry to six equivalent Cu(1) atoms. La(1) is bonded in a 8-coordinate geometry to eight equivalent Cu(1) atoms. Cu(1) is bonded in a 7-coordinate geometry to three equivalent Mg(1) and four equivalent La(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
