Materials Data on LuAl3 by Materials Project
LuAl3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Lu is bonded to twelve equivalent Al atoms to form a mixture of face and corner-sharing LuAl12 cuboctahedra. There are six shorter (3.03 Å) and six longer (3.07 Å) Lu–Al bond lengths. Al is bonded in a 10-coordinate geometry to four equivalent Lu and six equivalent Al atoms. There are two shorter (2.77 Å) and four longer (2.82 Å) Al–Al bond lengths.
