The material described by Pa3Ce 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 Ce(1) atoms to form PaCe4Pa8 cuboctahedra that share corners with twelve equivalent Pa(1)Ce4Pa8 cuboctahedra, edges with eight equivalent Ce(1)Pa12 cuboctahedra, edges with sixteen equivalent Pa(1)Ce4Pa8 cuboctahedra, faces with four equivalent Ce(1)Pa12 cuboctahedra, and faces with fourteen equivalent Pa(1)Ce4Pa8 cuboctahedra. Ce(1) is bonded to twelve equivalent Pa(1) atoms to form CePa12 cuboctahedra that share corners with twelve equivalent Ce(1)Pa12 cuboctahedra, edges with twenty-four equivalent Pa(1)Ce4Pa8 cuboctahedra, faces with six equivalent Ce(1)Pa12 cuboctahedra, and faces with twelve equivalent Pa(1)Ce4Pa8 cuboctahedra. is represented by the CIF card [CIF]
