Materials Data on YSi2Rh3 by Materials Project

Abstract

YRh3Si2 crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. Y is bonded in a 8-coordinate geometry to two equivalent Y, twelve Rh, and six equivalent Si atoms. Both Y–Y bond lengths are 3.62 Å. There are a spread of Y–Rh bond distances ranging from 3.09–3.55 Å. There are a spread of Y–Si bond distances ranging from 3.16–3.30 Å. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 12-coordinate geometry to four equivalent Y and four equivalent Si atoms. All Rh–Si bond lengths are 2.46 Å. In the second Rh site, Rh is bonded in a 4-coordinate geometry to four equivalent Y and four equivalent Si atoms. There are two shorter (2.41 Å) and two longer (2.44 Å) Rh–Si bond lengths. Si is bonded in a 6-coordinate geometry to three equivalent Y and six Rh atoms.
