Ho3Nd is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Ho(1) is bonded to eight equivalent Ho(1) and four equivalent Nd(1) atoms to form HoNd4Ho8 cuboctahedra that share corners with twelve equivalent Ho(1)Nd4Ho8 cuboctahedra, edges with eight equivalent Nd(1)Ho12 cuboctahedra, edges with sixteen equivalent Ho(1)Nd4Ho8 cuboctahedra, faces with four equivalent Nd(1)Ho12 cuboctahedra, and faces with fourteen equivalent Ho(1)Nd4Ho8 cuboctahedra. Nd(1) is bonded to twelve equivalent Ho(1) atoms to form NdHo12 cuboctahedra that share corners with twelve equivalent Nd(1)Ho12 cuboctahedra, edges with twenty-four equivalent Ho(1)Nd4Ho8 cuboctahedra, faces with six equivalent Nd(1)Ho12 cuboctahedra, and faces with twelve equivalent Ho(1)Nd4Ho8 cuboctahedra.
