The material structure described by Yb3Ho is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Yb(1) is bonded to eight equivalent Yb(1) and four equivalent Ho(1) atoms to form YbYb8Ho4 cuboctahedra that share corners with four equivalent Ho(1)Yb12 cuboctahedra, corners with fourteen equivalent Yb(1)Yb8Ho4 cuboctahedra, edges with six equivalent Ho(1)Yb12 cuboctahedra, edges with twelve equivalent Yb(1)Yb8Ho4 cuboctahedra, faces with four equivalent Ho(1)Yb12 cuboctahedra, and faces with sixteen equivalent Yb(1)Yb8Ho4 cuboctahedra. Ho(1) is bonded to twelve equivalent Yb(1) atoms to form HoYb12 cuboctahedra that share corners with six equivalent Ho(1)Yb12 cuboctahedra, corners with twelve equivalent Yb(1)Yb8Ho4 cuboctahedra, edges with eighteen equivalent Yb(1)Yb8Ho4 cuboctahedra, faces with eight equivalent Ho(1)Yb12 cuboctahedra, and faces with twelve equivalent Yb(1)Yb8Ho4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
