PrCeAl4 is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. Pr(1) is bonded in a 16-coordinate geometry to four equivalent Ce(1) and twelve equivalent Al(1) atoms. Ce(1) is bonded in a 16-coordinate geometry to four equivalent Pr(1) and twelve equivalent Al(1) atoms. Al(1) is bonded to three equivalent Pr(1), three equivalent Ce(1), and six equivalent Al(1) atoms to form a mixture of face, corner, and edge-sharing AlCe3Pr3Al6 cuboctahedra.
PrCeAl4 is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. Pr(1) is bonded in a 16-coordinate geometry to four equivalent Ce(1) and twelve equivalent Al(1) atoms. All Pr(1)-Ce(1) bond lengths are 3.47 Å. All Pr(1)-Al(1) bond lengths are 3.32 Å. Ce(1) is bonded in a 16-coordinate geometry to four equivalent Pr(1) and twelve equivalent Al(1) atoms. All Ce(1)-Al(1) bond lengths are 3.32 Å. Al(1) is bonded to three equivalent Pr(1), three equivalent Ce(1), and six equivalent Al(1) atoms to form a mixture of face, corner, and edge-sharing AlCe3Pr3Al6 cuboctahedra. There are three shorter (2.82 Å) and three longer (2.84 Å) Al(1)-Al(1) bond lengths.
