TmAuNi4 is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. Tm(1) is bonded in a 16-coordinate geometry to twelve equivalent Ni(1) and four equivalent Au(1) atoms. Ni(1) is bonded to three equivalent Tm(1), six equivalent Ni(1), and three equivalent Au(1) atoms to form a mixture of face, edge, and corner-sharing NiTm3Ni6Au3 cuboctahedra. Au(1) is bonded in a 16-coordinate geometry to four equivalent Tm(1) and twelve equivalent Ni(1) atoms.
TmAuNi4 is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. Tm(1) is bonded in a 16-coordinate geometry to twelve equivalent Ni(1) and four equivalent Au(1) atoms. All Tm(1)-Ni(1) bond lengths are 2.85 Å. All Tm(1)-Au(1) bond lengths are 2.97 Å. Ni(1) is bonded to three equivalent Tm(1), six equivalent Ni(1), and three equivalent Au(1) atoms to form a mixture of face, edge, and corner-sharing NiTm3Ni6Au3 cuboctahedra. There are three shorter (2.41 Å) and three longer (2.44 Å) Ni(1)-Ni(1) bond lengths. All Ni(1)-Au(1) bond lengths are 2.84 Å. Au(1) is bonded in a 16-coordinate geometry to four equivalent Tm(1) and twelve equivalent Ni(1) atoms.
