Dy3Bi is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Dy(1) is bonded to eight equivalent Dy(1) and four equivalent Bi(1) atoms to form distorted DyDy8Bi4 cuboctahedra that share corners with twelve equivalent Dy(1)Dy8Bi4 cuboctahedra, edges with eight equivalent Bi(1)Dy12 cuboctahedra, edges with sixteen equivalent Dy(1)Dy8Bi4 cuboctahedra, faces with four equivalent Bi(1)Dy12 cuboctahedra, and faces with fourteen equivalent Dy(1)Dy8Bi4 cuboctahedra. Bi(1) is bonded to twelve equivalent Dy(1) atoms to form BiDy12 cuboctahedra that share corners with twelve equivalent Bi(1)Dy12 cuboctahedra, edges with twenty-four equivalent Dy(1)Dy8Bi4 cuboctahedra, faces with six equivalent Bi(1)Dy12 cuboctahedra, and faces with twelve equivalent Dy(1)Dy8Bi4 cuboctahedra.
