Pa3Cd 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 Cd(1) atoms to form PaPa8Cd4 cuboctahedra that share corners with twelve equivalent Pa(1)Pa8Cd4 cuboctahedra, edges with eight equivalent Cd(1)Pa12 cuboctahedra, edges with sixteen equivalent Pa(1)Pa8Cd4 cuboctahedra, faces with four equivalent Cd(1)Pa12 cuboctahedra, and faces with fourteen equivalent Pa(1)Pa8Cd4 cuboctahedra. Cd(1) is bonded to twelve equivalent Pa(1) atoms to form CdPa12 cuboctahedra that share corners with twelve equivalent Cd(1)Pa12 cuboctahedra, edges with twenty-four equivalent Pa(1)Pa8Cd4 cuboctahedra, faces with six equivalent Cd(1)Pa12 cuboctahedra, and faces with twelve equivalent Pa(1)Pa8Cd4 cuboctahedra.
