The structure described by PmCe3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Pm(1) is bonded to twelve equivalent Ce(1) atoms to form PmCe12 cuboctahedra that share corners with twelve equivalent Pm(1)Ce12 cuboctahedra, edges with twenty-four equivalent Ce(1)Ce8Pm4 cuboctahedra, faces with six equivalent Pm(1)Ce12 cuboctahedra, and faces with twelve equivalent Ce(1)Ce8Pm4 cuboctahedra. Ce(1) is bonded to four equivalent Pm(1) and eight equivalent Ce(1) atoms to form CeCe8Pm4 cuboctahedra that share corners with twelve equivalent Ce(1)Ce8Pm4 cuboctahedra, edges with eight equivalent Pm(1)Ce12 cuboctahedra, edges with sixteen equivalent Ce(1)Ce8Pm4 cuboctahedra, faces with four equivalent Pm(1)Ce12 cuboctahedra, and faces with fourteen equivalent Ce(1)Ce8Pm4 cuboctahedra. is represented by the CIF file [CIF]
