UAl3 crystallizes in the hexagonal P6_3/mmc space group. U(1) is bonded to twelve equivalent Al(1) atoms to form a mixture of distorted face and corner-sharing UAl12 cuboctahedra. Al(1) is bonded in a 10-coordinate geometry to four equivalent U(1) and six equivalent Al(1) atoms.
UAl3 crystallizes in the hexagonal P6_3/mmc space group. U(1) is bonded to twelve equivalent Al(1) atoms to form a mixture of distorted face and corner-sharing UAl12 cuboctahedra. There are six shorter (3.06 Å) and six longer (3.19 Å) U(1)-Al(1) bond lengths. Al(1) is bonded in a 10-coordinate geometry to four equivalent U(1) and six equivalent Al(1) atoms. All Al(1)-Al(1) bond lengths are 2.75 Å.
