Materials Data on HoAl3 by Materials Project

Abstract

HoAl3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Ho is bonded to twelve equivalent Al atoms to form HoAl12 cuboctahedra that share corners with twelve equivalent HoAl12 cuboctahedra, edges with twenty-four equivalent AlHo4Al8 cuboctahedra, faces with six equivalent HoAl12 cuboctahedra, and faces with twelve equivalent AlHo4Al8 cuboctahedra. All Ho–Al bond lengths are 3.00 Å. Al is bonded to four equivalent Ho and eight equivalent Al atoms to form distorted AlHo4Al8 cuboctahedra that share corners with twelve equivalent AlHo4Al8 cuboctahedra, edges with eight equivalent HoAl12 cuboctahedra, edges with sixteen equivalent AlHo4Al8 cuboctahedra, faces with four equivalent HoAl12 cuboctahedra, and faces with fourteen equivalent AlHo4Al8 cuboctahedra. All Al–Al bond lengths are 3.00 Å.
