UCo4Sn crystallizes in the cubic F-43m space group. U(1) is bonded in a 16-coordinate geometry to twelve equivalent Co(1) and four equivalent Sn(1) atoms. Co(1) is bonded to three equivalent U(1), six equivalent Co(1), and three equivalent Sn(1) atoms to form a mixture of face, corner, and edge-sharing CoU3Co6Sn3 cuboctahedra. Sn(1) is bonded in a 16-coordinate geometry to four equivalent U(1) and twelve equivalent Co(1) atoms.
UCo4Sn crystallizes in the cubic F-43m space group. U(1) is bonded in a 16-coordinate geometry to twelve equivalent Co(1) and four equivalent Sn(1) atoms. All U(1)-Co(1) bond lengths are 2.90 Å. All U(1)-Sn(1) bond lengths are 3.03 Å. Co(1) is bonded to three equivalent U(1), six equivalent Co(1), and three equivalent Sn(1) atoms to form a mixture of face, corner, and edge-sharing CoU3Co6Sn3 cuboctahedra. There are three shorter (2.44 Å) and three longer (2.50 Å) Co(1)-Co(1) bond lengths. All Co(1)-Sn(1) bond lengths are 2.89 Å. Sn(1) is bonded in a 16-coordinate geometry to four equivalent U(1) and twelve equivalent Co(1) atoms.
