Materials Data on DyHo3 by Materials Project

Ho3Dy is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Ho is bonded to eight equivalent Ho and four equivalent Dy atoms to form HoDy4Ho8 cuboctahedra that share corners with twelve equivalent HoDy4Ho8 cuboctahedra, edges with eight equivalent DyHo12 cuboctahedra, edges with sixteen equivalent HoDy4Ho8 cuboctahedra, faces with four equivalent DyHo12 cuboctahedra, and faces with fourteen equivalent HoDy4Ho8 cuboctahedra. All Ho–Ho bond lengths are 3.53 Å. All Ho–Dy bond lengths are 3.53 Å. Dy is bonded to twelve equivalent Ho atoms to form DyHo12 cuboctahedra that share corners with twelve equivalent DyHo12 cuboctahedra, edges with twenty-four equivalent HoDy4Ho8 cuboctahedra, faces with six equivalent DyHo12 cuboctahedra, and faces with twelve equivalent HoDy4Ho8 cuboctahedra.
