UAl3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. U(1) is bonded to twelve equivalent Al(1) atoms to form UAl12 cuboctahedra that share corners with twelve equivalent U(1)Al12 cuboctahedra, edges with twenty-four equivalent Al(1)U4Al8 cuboctahedra, faces with six equivalent U(1)Al12 cuboctahedra, and faces with twelve equivalent Al(1)U4Al8 cuboctahedra. Al(1) is bonded to four equivalent U(1) and eight equivalent Al(1) atoms to form AlU4Al8 cuboctahedra that share corners with twelve equivalent Al(1)U4Al8 cuboctahedra, edges with eight equivalent U(1)Al12 cuboctahedra, edges with sixteen equivalent Al(1)U4Al8 cuboctahedra, faces with four equivalent U(1)Al12 cuboctahedra, and faces with fourteen equivalent Al(1)U4Al8 cuboctahedra.
