Materials Data on Yb5(Ge5Rh2)2 by Materials Project
Yb5Rh4Ge10 crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. there are three inequivalent Yb sites. In the first Yb site, Yb is bonded in a 8-coordinate geometry to four equivalent Rh and twelve Ge atoms. All Yb–Rh bond lengths are 3.24 Å. There are eight shorter (2.98 Å) and four longer (3.31 Å) Yb–Ge bond lengths. In the second Yb site, Yb is bonded to four equivalent Rh and eight Ge atoms to form face-sharing YbGe8Rh4 cuboctahedra. All Yb–Rh bond lengths are 3.09 Å. There are a spread of Yb–Ge bond distances ranging from 2.98–3.14 Å. In the third Yb site, Yb is bonded in a 8-coordinate geometry to four equivalent Rh and ten Ge atoms. All Yb–Rh bond lengths are 3.37 Å. There are a spread of Yb–Ge bond distances ranging from 3.23–3.37 Å. Rh is bonded in a 10-coordinate geometry to five Yb and five Ge atoms. There are a spread of Rh–Ge bond distances ranging from 2.45–2.56 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to six Yb, two equivalent Rh, and one Ge atom. The Ge–Ge bond length is 2.41 Å. In the second Ge site, Ge is bonded in a 2-coordinate geometry to five Yb, two equivalent Rh, and one Ge atom. The Ge–Ge bond length is 2.63 Å. In the third Ge site, Ge is bonded in a 2-coordinate geometry to four Yb, two equivalent Rh, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.87 Å.
