Pm3Ag is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Pm(1) is bonded in a distorted see-saw-like geometry to four equivalent Ag(1) atoms. Ag(1) is bonded to twelve equivalent Pm(1) atoms to form a mixture of face and corner-sharing AgPm12 cuboctahedra.
Pm3Ag is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Pm(1) is bonded in a distorted see-saw-like geometry to four equivalent Ag(1) atoms. There are two shorter (3.35 Å) and two longer (3.53 Å) Pm(1)-Ag(1) bond lengths. Ag(1) is bonded to twelve equivalent Pm(1) atoms to form a mixture of face and corner-sharing AgPm12 cuboctahedra.
