Materials Data on CeSi2Rh3 by Materials Project
CeRh3Si2 crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. Ce is bonded in a 12-coordinate geometry to two equivalent Ce, twelve Rh, and six equivalent Si atoms. Both Ce–Ce bond lengths are 3.61 Å. There are a spread of Ce–Rh bond distances ranging from 3.11–3.56 Å. There are a spread of Ce–Si bond distances ranging from 3.17–3.36 Å. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 12-coordinate geometry to four equivalent Ce and four equivalent Si atoms. All Rh–Si bond lengths are 2.46 Å. In the second Rh site, Rh is bonded in a 6-coordinate geometry to four equivalent Ce and four equivalent Si atoms. There are two shorter (2.43 Å) and two longer (2.44 Å) Rh–Si bond lengths. Si is bonded in a 6-coordinate geometry to three equivalent Ce and six Rh atoms.
