Ho3(Ni3Al)2 crystallizes in the cubic Im-3m space group. Ho(1) is bonded in a 12-coordinate geometry to eight equivalent Ni(1) and four equivalent Al(1) atoms. Ni(1) is bonded in a 10-coordinate geometry to four equivalent Ho(1), four equivalent Ni(1), and two equivalent Al(1) atoms. Al(1) is bonded in a distorted hexagonal planar geometry to six equivalent Ho(1) and six equivalent Ni(1) atoms.
Ho3(Ni3Al)2 crystallizes in the cubic Im-3m space group. Ho(1) is bonded in a 12-coordinate geometry to eight equivalent Ni(1) and four equivalent Al(1) atoms. There are four shorter (2.75 Å) and four longer (2.97 Å) Ho(1)-Ni(1) bond lengths. All Ho(1)-Al(1) bond lengths are 3.14 Å. Ni(1) is bonded in a 10-coordinate geometry to four equivalent Ho(1), four equivalent Ni(1), and two equivalent Al(1) atoms. All Ni(1)-Ni(1) bond lengths are 2.55 Å. Both Ni(1)-Al(1) bond lengths are 2.44 Å. Al(1) is bonded in a distorted hexagonal planar geometry to six equivalent Ho(1) and six equivalent Ni(1) atoms.
