Materials Data on UAl3 by Materials Project
UAl3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. U is bonded to twelve equivalent Al atoms to form UAl12 cuboctahedra that share corners with twelve equivalent UAl12 cuboctahedra, edges with twenty-four equivalent AlU4Al8 cuboctahedra, faces with six equivalent UAl12 cuboctahedra, and faces with twelve equivalent AlU4Al8 cuboctahedra. All U–Al bond lengths are 3.01 Å. Al is bonded to four equivalent U and eight equivalent Al atoms to form AlU4Al8 cuboctahedra that share corners with twelve equivalent AlU4Al8 cuboctahedra, edges with eight equivalent UAl12 cuboctahedra, edges with sixteen equivalent AlU4Al8 cuboctahedra, faces with four equivalent UAl12 cuboctahedra, and faces with fourteen equivalent AlU4Al8 cuboctahedra. All Al–Al bond lengths are 3.01 Å.
