UNi4Sn crystallizes in the cubic F-43m space group. U(1) is bonded in a 16-coordinate geometry to twelve equivalent Ni(1) and four equivalent Sn(1) atoms. Ni(1) is bonded to three equivalent U(1), six equivalent Ni(1), and three equivalent Sn(1) atoms to form a mixture of face, corner, and edge-sharing NiU3Ni6Sn3 cuboctahedra. Sn(1) is bonded in a 16-coordinate geometry to four equivalent U(1) and twelve equivalent Ni(1) atoms.
UNi4Sn crystallizes in the cubic F-43m space group. U(1) is bonded in a 16-coordinate geometry to twelve equivalent Ni(1) and four equivalent Sn(1) atoms. All U(1)-Ni(1) bond lengths are 2.91 Å. All U(1)-Sn(1) bond lengths are 3.04 Å. Ni(1) is bonded to three equivalent U(1), six equivalent Ni(1), and three equivalent Sn(1) atoms to form a mixture of face, corner, and edge-sharing NiU3Ni6Sn3 cuboctahedra. There are three shorter (2.48 Å) and three longer (2.49 Å) Ni(1)-Ni(1) bond lengths. All Ni(1)-Sn(1) bond lengths are 2.91 Å. Sn(1) is bonded in a 16-coordinate geometry to four equivalent U(1) and twelve equivalent Ni(1) atoms.
