Materials Data on YbPm3 by Materials Project
YbPm3 is Magnesium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Yb is bonded to twelve equivalent Pm atoms to form YbPm12 cuboctahedra that share corners with six equivalent YbPm12 cuboctahedra, corners with twelve equivalent PmYb4Pm8 cuboctahedra, edges with eighteen equivalent PmYb4Pm8 cuboctahedra, faces with eight equivalent YbPm12 cuboctahedra, and faces with twelve equivalent PmYb4Pm8 cuboctahedra. There are six shorter (3.68 Å) and six longer (3.70 Å) Yb–Pm bond lengths. Pm is bonded to four equivalent Yb and eight equivalent Pm atoms to form PmYb4Pm8 cuboctahedra that share corners with four equivalent YbPm12 cuboctahedra, corners with fourteen equivalent PmYb4Pm8 cuboctahedra, edges with six equivalent YbPm12 cuboctahedra, edges with twelve equivalent PmYb4Pm8 cuboctahedra, faces with four equivalent YbPm12 cuboctahedra, and faces with sixteen equivalent PmYb4Pm8 cuboctahedra. There are a spread of Pm–Pm bond distances ranging from 3.64–3.75 Å.
