Materials Data on NdSi2Rh3 by Materials Project

Abstract

NdRh3Si2 crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. Nd is bonded in a 8-coordinate geometry to two equivalent Nd, twelve Rh, and six equivalent Si atoms. Both Nd–Nd bond lengths are 3.62 Å. There are a spread of Nd–Rh bond distances ranging from 3.13–3.58 Å. There are a spread of Nd–Si bond distances ranging from 3.21–3.34 Å. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 12-coordinate geometry to four equivalent Nd and four equivalent Si atoms. All Rh–Si bond lengths are 2.48 Å. In the second Rh site, Rh is bonded in a 4-coordinate geometry to four equivalent Nd and four equivalent Si atoms. There are two shorter (2.43 Å) and two longer (2.45 Å) Rh–Si bond lengths. Si is bonded in a 10-coordinate geometry to three equivalent Nd and six Rh atoms.
