The crystal structure described by Pa3Nd 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 Nd(1) atoms to form PaNd4Pa8 cuboctahedra that share corners with twelve equivalent Pa(1)Nd4Pa8 cuboctahedra, edges with eight equivalent Nd(1)Pa12 cuboctahedra, edges with sixteen equivalent Pa(1)Nd4Pa8 cuboctahedra, faces with four equivalent Nd(1)Pa12 cuboctahedra, and faces with fourteen equivalent Pa(1)Nd4Pa8 cuboctahedra. Nd(1) is bonded to twelve equivalent Pa(1) atoms to form NdPa12 cuboctahedra that share corners with twelve equivalent Nd(1)Pa12 cuboctahedra, edges with twenty-four equivalent Pa(1)Nd4Pa8 cuboctahedra, faces with six equivalent Nd(1)Pa12 cuboctahedra, and faces with twelve equivalent Pa(1)Nd4Pa8 cuboctahedra. is represented by the CIF card [CIF]
