LuPdAl crystallizes in the hexagonal P-62m space group. Lu(1) is bonded in a 11-coordinate geometry to one Pd(1), four equivalent Pd(2), and six equivalent Al(1) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 9-coordinate geometry to three equivalent Lu(1) and six equivalent Al(1) atoms. In the second Pd site, Pd(2) is bonded in a 9-coordinate geometry to six equivalent Lu(1) and three equivalent Al(1) atoms. Al(1) is bonded in a 4-coordinate geometry to six equivalent Lu(1), two equivalent Pd(1), and two equivalent Pd(2) atoms.
LuPdAl crystallizes in the hexagonal P-62m space group. Lu(1) is bonded in a 11-coordinate geometry to one Pd(1), four equivalent Pd(2), and six equivalent Al(1) atoms. The Lu(1)-Pd(1) bond length is 2.99 Å. All Lu(1)-Pd(2) bond lengths are 2.87 Å. There are two shorter (3.08 Å) and four longer (3.20 Å) Lu(1)-Al(1) bond lengths. There are two inequivalent Pd sites.
