Materials Data on Yb(As2Rh3)2 by Materials Project
Yb(Rh3As2)2 crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Yb is bonded to six equivalent Rh and six equivalent As atoms to form face-sharing YbAs6Rh6 cuboctahedra. All Yb–Rh bond lengths are 3.15 Å. All Yb–As bond lengths are 3.05 Å. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 5-coordinate geometry to five As atoms. There are one shorter (2.55 Å) and four longer (2.59 Å) Rh–As bond lengths. In the second Rh site, Rh is bonded in a 6-coordinate geometry to two equivalent Yb and four As atoms. There are two shorter (2.45 Å) and two longer (2.55 Å) Rh–As bond lengths. There are two inequivalent As sites. In the first As site, As is bonded in a 8-coordinate geometry to two equivalent Yb and six Rh atoms. In the second As site, As is bonded in a 9-coordinate geometry to nine Rh atoms.
