PmAg3 crystallizes in the hexagonal P6_3/mmc space group. Pm(1) is bonded to twelve equivalent Ag(1) atoms to form a mixture of face and corner-sharing PmAg12 cuboctahedra. Ag(1) is bonded in a 10-coordinate geometry to four equivalent Pm(1) and six equivalent Ag(1) atoms.
PmAg3 crystallizes in the hexagonal P6_3/mmc space group. Pm(1) is bonded to twelve equivalent Ag(1) atoms to form a mixture of face and corner-sharing PmAg12 cuboctahedra. There are six shorter (3.16 Å) and six longer (3.23 Å) Pm(1)-Ag(1) bond lengths. Ag(1) is bonded in a 10-coordinate geometry to four equivalent Pm(1) and six equivalent Ag(1) atoms. There are two shorter (2.90 Å) and four longer (2.93 Å) Ag(1)-Ag(1) bond lengths.
