Materials Data on CeLuAl4 by Materials Project
LuCeAl4 is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Lu is bonded in a 12-coordinate geometry to four equivalent Ce and twelve equivalent Al atoms. All Lu–Ce bond lengths are 3.40 Å. All Lu–Al bond lengths are 3.26 Å. Ce is bonded in a 12-coordinate geometry to four equivalent Lu and twelve equivalent Al atoms. All Ce–Al bond lengths are 3.26 Å. Al is bonded to three equivalent Lu, three equivalent Ce, and six equivalent Al atoms to form a mixture of edge, face, and corner-sharing AlCe3Lu3Al6 cuboctahedra. There are three shorter (2.77 Å) and three longer (2.79 Å) Al–Al bond lengths.
