Title: Materials Data on U2Al3Os by Materials Project

Abstract

U2OsAl3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. U is bonded in a 3-coordinate geometry to four equivalent U, three equivalent Os, and nine equivalent Al atoms. There are three shorter (3.22 Å) and one longer (3.53 Å) U–U bond lengths. All U–Os bond lengths are 3.12 Å. There are three shorter (3.10 Å) and six longer (3.20 Å) U–Al bond lengths. Os is bonded to six equivalent U and six equivalent Al atoms to form OsU6Al6 cuboctahedra that share corners with twelve equivalent AlU6Al4Os2 cuboctahedra, edges with six equivalent OsU6Al6 cuboctahedra, faces with two equivalent OsU6Al6 cuboctahedra, and faces with eighteen equivalent AlU6Al4Os2 cuboctahedra. All Os–Al bond lengths are 2.70 Å. Al is bonded to six equivalent U, two equivalent Os, and four equivalent Al atoms to form distorted AlU6Al4Os2 cuboctahedra that share corners with four equivalent OsU6Al6 cuboctahedra, corners with fourteen equivalent AlU6Al4Os2 cuboctahedra, edges with six equivalent AlU6Al4Os2 cuboctahedra, faces with six equivalent OsU6Al6 cuboctahedra, and faces with twelve equivalent AlU6Al4Os2 cuboctahedra. There are two shorter (2.65 Å) and two longer (2.69 Å) Al–Al bond lengths.
