PmZn3 crystallizes in the hexagonal P6_3/mmc space group. Pm(1) is bonded in a 12-coordinate geometry to twelve equivalent Zn(1) atoms. Zn(1) is bonded in a 10-coordinate geometry to four equivalent Pm(1) and six equivalent Zn(1) atoms.
PmZn3 crystallizes in the hexagonal P6_3/mmc space group. Pm(1) is bonded in a 12-coordinate geometry to twelve equivalent Zn(1) atoms. There are six shorter (3.04 Å) and six longer (3.23 Å) Pm(1)-Zn(1) bond lengths. Zn(1) is bonded in a 10-coordinate geometry to four equivalent Pm(1) and six equivalent Zn(1) atoms. There are four shorter (2.68 Å) and two longer (2.74 Å) Zn(1)-Zn(1) bond lengths.
