The material described by PmRh3 crystallizes in the hexagonal P6_3/mmc space group. Pm(1) is bonded to twelve equivalent Rh(1) atoms to form a mixture of face and corner-sharing PmRh12 cuboctahedra. Rh(1) is bonded in a 4-coordinate geometry to four equivalent Pm(1) atoms. is represented by the CIF file [CIF]
