Pa3Dy is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Pa(1) is bonded to eight equivalent Pa(1) and four equivalent Dy(1) atoms to form PaDy4Pa8 cuboctahedra that share corners with twelve equivalent Pa(1)Dy4Pa8 cuboctahedra, edges with eight equivalent Dy(1)Pa12 cuboctahedra, edges with sixteen equivalent Pa(1)Dy4Pa8 cuboctahedra, faces with four equivalent Dy(1)Pa12 cuboctahedra, and faces with fourteen equivalent Pa(1)Dy4Pa8 cuboctahedra. Dy(1) is bonded to twelve equivalent Pa(1) atoms to form DyPa12 cuboctahedra that share corners with twelve equivalent Dy(1)Pa12 cuboctahedra, edges with twenty-four equivalent Pa(1)Dy4Pa8 cuboctahedra, faces with six equivalent Dy(1)Pa12 cuboctahedra, and faces with twelve equivalent Pa(1)Dy4Pa8 cuboctahedra.
