Pm3Zn crystallizes in the hexagonal P6_3/mmc space group. Pm(1) is bonded in a 12-coordinate geometry to eight equivalent Pm(1) and four equivalent Zn(1) atoms. Zn(1) is bonded to twelve equivalent Pm(1) atoms to form a mixture of face and corner-sharing ZnPm12 cuboctahedra.
Pm3Zn crystallizes in the hexagonal P6_3/mmc space group. Pm(1) is bonded in a 12-coordinate geometry to eight equivalent Pm(1) and four equivalent Zn(1) atoms. There are a spread of Pm(1)-Pm(1) bond distances ranging from 3.27-3.78 Å. There are two shorter (3.22 Å) and two longer (3.53 Å) Pm(1)-Zn(1) bond lengths. Zn(1) is bonded to twelve equivalent Pm(1) atoms to form a mixture of face and corner-sharing ZnPm12 cuboctahedra.
