Materials Data on Si2Rh3 by Materials Project
Rh3Si2 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. there are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 5-coordinate geometry to five equivalent Si atoms. There are a spread of Rh–Si bond distances ranging from 2.40–2.70 Å. In the second Rh site, Rh is bonded in a 6-coordinate geometry to six equivalent Si atoms. All Rh–Si bond lengths are 2.53 Å. Si is bonded in a body-centered cubic geometry to eight Rh atoms.
