Materials Data on Pr2SiRh3 by Materials Project
Pr2Rh3Si crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Pr is bonded in a 9-coordinate geometry to nine equivalent Rh atoms. There are three shorter (2.94 Å) and six longer (3.25 Å) Pr–Rh bond lengths. Rh is bonded in a 12-coordinate geometry to six equivalent Pr, four equivalent Rh, and two equivalent Si atoms. All Rh–Rh bond lengths are 2.86 Å. Both Rh–Si bond lengths are 2.58 Å. Si is bonded to six equivalent Rh atoms to form distorted corner-sharing SiRh6 cuboctahedra.
