Materials Data on U2SnIr2 by Materials Project
U2Ir2Sn crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. U is bonded in a 6-coordinate geometry to six equivalent Ir and four equivalent Sn atoms. There are two shorter (2.77 Å) and four longer (2.94 Å) U–Ir bond lengths. All U–Sn bond lengths are 3.36 Å. Ir is bonded in a 6-coordinate geometry to six equivalent U, one Ir, and two equivalent Sn atoms. The Ir–Ir bond length is 2.90 Å. Both Ir–Sn bond lengths are 3.00 Å. Sn is bonded to eight equivalent U and four equivalent Ir atoms to form a mixture of corner and face-sharing SnU8Ir4 cuboctahedra.
