Materials Data on PmGe3 by Materials Project
PmGe3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Pm is bonded to twelve equivalent Ge atoms to form a mixture of corner and face-sharing PmGe12 cuboctahedra. There are six shorter (3.11 Å) and six longer (3.25 Å) Pm–Ge bond lengths. Ge is bonded in a 4-coordinate geometry to four equivalent Pm and six equivalent Ge atoms. There are two shorter (2.73 Å) and four longer (3.01 Å) Ge–Ge bond lengths.
