The material structure described by GdNi4Mg is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. Mg(1) is bonded in a 16-coordinate geometry to four equivalent Gd(1) and twelve equivalent Ni(1) atoms. Gd(1) is bonded in a 16-coordinate geometry to four equivalent Mg(1) and twelve equivalent Ni(1) atoms. Ni(1) is bonded to three equivalent Mg(1), three equivalent Gd(1), and six equivalent Ni(1) atoms to form a mixture of edge, face, and corner-sharing NiGd3Mg3Ni6 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
