Materials Data on YbPm3 by Materials Project

Abstract

YbPm3 is alpha La-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Yb is bonded to twelve Pm atoms to form YbPm12 cuboctahedra that share corners with four equivalent YbPm12 cuboctahedra, corners with eight equivalent PmYb4Pm8 cuboctahedra, edges with eight equivalent YbPm12 cuboctahedra, edges with sixteen equivalent PmYb4Pm8 cuboctahedra, faces with four equivalent YbPm12 cuboctahedra, and faces with fourteen PmYb4Pm8 cuboctahedra. All Yb–Pm bond lengths are 3.67 Å. There are two inequivalent Pm sites. In the first Pm site, Pm is bonded to four equivalent Yb and eight Pm atoms to form PmYb4Pm8 cuboctahedra that share corners with twelve equivalent PmYb4Pm8 cuboctahedra, edges with eight equivalent YbPm12 cuboctahedra, edges with sixteen PmYb4Pm8 cuboctahedra, faces with four equivalent YbPm12 cuboctahedra, and faces with fourteen PmYb4Pm8 cuboctahedra. All Pm–Pm bond lengths are 3.67 Å. In the second Pm site, Pm is bonded to four equivalent Yb and eight equivalent Pm atoms to form PmYb4Pm8 cuboctahedra that share corners with four equivalent PmYb4Pm8 cuboctahedra, corners with eight equivalent YbPm12 cuboctahedra, edges with twenty-four PmYb4Pm8 cuboctahedra, faces with six equivalent YbPm12 cuboctahedra, and faces with twelve PmYb4Pm8 cuboctahedra.
