Materials Data on Yb4Sb6Rh7 by Materials Project

Abstract

Yb4Rh7Sb6 crystallizes in the cubic Im-3m space group. The structure is three-dimensional. Yb is bonded to six equivalent Rh and six equivalent Sb atoms to form YbSb6Rh6 cuboctahedra that share corners with twelve equivalent YbSb6Rh6 cuboctahedra, faces with six equivalent YbSb6Rh6 cuboctahedra, and faces with two equivalent RhSb6 octahedra. All Yb–Rh bond lengths are 3.10 Å. All Yb–Sb bond lengths are 3.15 Å. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 12-coordinate geometry to four equivalent Yb and four equivalent Sb atoms. All Rh–Sb bond lengths are 2.71 Å. In the second Rh site, Rh is bonded to six equivalent Sb atoms to form RhSb6 octahedra that share faces with eight equivalent YbSb6Rh6 cuboctahedra. All Rh–Sb bond lengths are 2.78 Å. Sb is bonded in a 9-coordinate geometry to four equivalent Yb and five Rh atoms.
