The material structure described by Ho3Y is Magnesium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded to eight Ho(1,1) and four equivalent Y(1) atoms to form HoY4Ho8 cuboctahedra that share corners with four equivalent Y(1)Ho12 cuboctahedra; corners with fourteen equivalent Ho(1)Y4Ho8 cuboctahedra; edges with six equivalent Y(1)Ho12 cuboctahedra; edges with twelve Ho(1,1)Y4Ho8 cuboctahedra; faces with four equivalent Y(1)Ho12 cuboctahedra; and faces with sixteen Ho(1,1)Y4Ho8 cuboctahedra. In the second Ho site, Ho(1) is bonded to eight equivalent Ho(1) and four equivalent Y(1) atoms to form HoY4Ho8 cuboctahedra that share corners with four equivalent Y(1)Ho12 cuboctahedra; corners with fourteen Ho(1,1)Y4Ho8 cuboctahedra; edges with six equivalent Y(1)Ho12 cuboctahedra; edges with twelve equivalent Ho(1)Y4Ho8 cuboctahedra; faces with four equivalent Y(1)Ho12 cuboctahedra; and faces with sixteen Ho(1,1)Y4Ho8 cuboctahedra.
