Materials Data on UCo4Sn by Materials Project
UCo4Sn crystallizes in the cubic F-43m space group. The structure is three-dimensional. U is bonded in a 12-coordinate geometry to twelve equivalent Co and four equivalent Sn atoms. All U–Co bond lengths are 2.90 Å. All U–Sn bond lengths are 3.03 Å. Co is bonded to three equivalent U, six equivalent Co, and three equivalent Sn atoms to form a mixture of corner, edge, and face-sharing CoU3Co6Sn3 cuboctahedra. There are three shorter (2.44 Å) and three longer (2.50 Å) Co–Co bond lengths. All Co–Sn bond lengths are 2.89 Å. Sn is bonded in a 4-coordinate geometry to four equivalent U and twelve equivalent Co atoms.
