The crystal structure described by Ho3Pr 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 Pr(1) atoms to form HoPr4Ho8 cuboctahedra that share corners with twelve equivalent Ho(1)Pr4Ho8 cuboctahedra, edges with eight equivalent Pr(1)Ho12 cuboctahedra, edges with sixteen equivalent Ho(1)Pr4Ho8 cuboctahedra, faces with four equivalent Pr(1)Ho12 cuboctahedra, and faces with fourteen equivalent Ho(1)Pr4Ho8 cuboctahedra. Pr(1) is bonded to twelve equivalent Ho(1) atoms to form PrHo12 cuboctahedra that share corners with twelve equivalent Pr(1)Ho12 cuboctahedra, edges with twenty-four equivalent Ho(1)Pr4Ho8 cuboctahedra, faces with six equivalent Pr(1)Ho12 cuboctahedra, and faces with twelve equivalent Ho(1)Pr4Ho8 cuboctahedra. is represented by the CIF file [CIF]
