Materials Data on Pr3Rh2 by Materials Project
Pr3Rh2 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. there are three inequivalent Pr sites. In the first Pr site, Pr is bonded in an octahedral geometry to six equivalent Rh atoms. All Pr–Rh bond lengths are 3.08 Å. In the second Pr site, Pr is bonded in a 6-coordinate geometry to six equivalent Rh atoms. There are three shorter (2.94 Å) and three longer (3.17 Å) Pr–Rh bond lengths. In the third Pr site, Pr is bonded in a 5-coordinate geometry to five equivalent Rh atoms. There are a spread of Pr–Rh bond distances ranging from 2.93–3.34 Å. Rh is bonded in a 8-coordinate geometry to eight Pr atoms.
