The crystal structure described by YbHo3 is beta Cu3Ti-like structured and crystallizes in the tetragonal I4/mmm space group. Yb(1) is bonded to four equivalent Ho(2) and eight equivalent Ho(1) atoms to form YbHo12 cuboctahedra that share corners with four equivalent Yb(1)Ho12 cuboctahedra, corners with eight equivalent Ho(2)Yb4Ho8 cuboctahedra, edges with eight equivalent Yb(1)Ho12 cuboctahedra, edges with sixteen equivalent Ho(1)Yb4Ho8 cuboctahedra, faces with four equivalent Yb(1)Ho12 cuboctahedra, faces with six equivalent Ho(2)Yb4Ho8 cuboctahedra, and faces with eight equivalent Ho(1)Yb4Ho8 cuboctahedra. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded to four equivalent Yb(1), four equivalent Ho(1), and four equivalent Ho(2) atoms to form HoYb4Ho8 cuboctahedra that share corners with twelve equivalent Ho(1)Yb4Ho8 cuboctahedra, edges with eight equivalent Yb(1)Ho12 cuboctahedra, edges with eight equivalent Ho(1)Yb4Ho8 cuboctahedra, edges with eight equivalent Ho(2)Yb4Ho8 cuboctahedra, faces with four equivalent Yb(1)Ho12 cuboctahedra, faces with four equivalent Ho(2)Yb4Ho8 cuboctahedra, and faces with ten equivalent Ho(1)Yb4Ho8 cuboctahedra. In the second Ho site, Ho(2) is bonded to four equivalent Yb(1) and eight equivalent Ho(1) atoms to form HoYb4Ho8 cuboctahedra that share corners with four equivalent Ho(2)Yb4Ho8 cuboctahedra, corners with eight equivalent Yb(1)Ho12 cuboctahedra, edges with eight equivalent Ho(2)Yb4Ho8 cuboctahedra, edges with sixteen equivalent Ho(1)Yb4Ho8 cuboctahedra, faces with four equivalent Ho(2)Yb4Ho8 cuboctahedra, faces with six equivalent Yb(1)Ho12 cuboctahedra, and faces with eight equivalent Ho(1)Yb4Ho8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
