Materials Data on U2Co2Sn by Materials Project
U2Co2Sn crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. U is bonded in a 6-coordinate geometry to six equivalent Co and four equivalent Sn atoms. There are two shorter (2.68 Å) and four longer (2.79 Å) U–Co bond lengths. All U–Sn bond lengths are 3.23 Å. Co is bonded in a 6-coordinate geometry to six equivalent U, one Co, and two equivalent Sn atoms. The Co–Co bond length is 2.80 Å. Both Co–Sn bond lengths are 2.86 Å. Sn is bonded to eight equivalent U and four equivalent Co atoms to form a mixture of distorted face and corner-sharing SnU8Co4 cuboctahedra.
