HoGa3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Ho(1) is bonded to twelve equivalent Ga(1) atoms to form HoGa12 cuboctahedra that share corners with twelve equivalent Ho(1)Ga12 cuboctahedra, edges with twenty-four equivalent Ga(1)Ho4Ga8 cuboctahedra, faces with six equivalent Ho(1)Ga12 cuboctahedra, and faces with twelve equivalent Ga(1)Ho4Ga8 cuboctahedra. Ga(1) is bonded to four equivalent Ho(1) and eight equivalent Ga(1) atoms to form distorted GaHo4Ga8 cuboctahedra that share corners with twelve equivalent Ga(1)Ho4Ga8 cuboctahedra, edges with eight equivalent Ho(1)Ga12 cuboctahedra, edges with sixteen equivalent Ga(1)Ho4Ga8 cuboctahedra, faces with four equivalent Ho(1)Ga12 cuboctahedra, and faces with fourteen equivalent Ga(1)Ho4Ga8 cuboctahedra.
