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