HoPrAl4 is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. Ho(1) is bonded in a 16-coordinate geometry to four equivalent Pr(1) and twelve equivalent Al(1) atoms. Pr(1) is bonded in a 16-coordinate geometry to four equivalent Ho(1) and twelve equivalent Al(1) atoms. Al(1) is bonded to three equivalent Ho(1), three equivalent Pr(1), and six equivalent Al(1) atoms to form a mixture of edge, face, and corner-sharing AlPr3Ho3Al6 cuboctahedra.
HoPrAl4 is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. Ho(1) is bonded in a 16-coordinate geometry to four equivalent Pr(1) and twelve equivalent Al(1) atoms. All Ho(1)-Pr(1) bond lengths are 3.44 Å. All Ho(1)-Al(1) bond lengths are 3.29 Å. Pr(1) is bonded in a 16-coordinate geometry to four equivalent Ho(1) and twelve equivalent Al(1) atoms. All Pr(1)-Al(1) bond lengths are 3.29 Å. Al(1) is bonded to three equivalent Ho(1), three equivalent Pr(1), and six equivalent Al(1) atoms to form a mixture of edge, face, and corner-sharing AlPr3Ho3Al6 cuboctahedra. There are three shorter (2.80 Å) and three longer (2.81 Å) Al(1)-Al(1) bond lengths.
