Title: Materials Data on Y4Si5Rh9 by Materials Project

Abstract

Y4Rh9Si5 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are two inequivalent Y sites. In the first Y site, Y is bonded in a 12-coordinate geometry to two Y, twelve Rh, and six Si atoms. There are one shorter (3.29 Å) and one longer (3.46 Å) Y–Y bond lengths. There are six shorter (3.27 Å) and six longer (3.38 Å) Y–Rh bond lengths. All Y–Si bond lengths are 3.21 Å. In the second Y site, Y is bonded in a 9-coordinate geometry to one Y and nine equivalent Rh atoms. There are three shorter (3.03 Å) and six longer (3.09 Å) Y–Rh bond lengths. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 12-coordinate geometry to five Y, four equivalent Rh, and three Si atoms. There are two shorter (2.77 Å) and two longer (2.78 Å) Rh–Rh bond lengths. There are two shorter (2.41 Å) and one longer (2.54 Å) Rh–Si bond lengths. In the second Rh site, Rh is bonded in a 4-coordinate geometry to four equivalent Y and four Si atoms. All Rh–Si bond lengths are 2.45 Å. There are three inequivalent Si sites. In the firstmore » Si site, Si is bonded in a 9-coordinate geometry to three equivalent Y and six Rh atoms. In the second Si site, Si is bonded in a distorted cuboctahedral geometry to six equivalent Rh atoms. In the third Si site, Si is bonded in a 9-coordinate geometry to three equivalent Y and six Rh atoms.« less
