Materials Data on YSiRh2 by Materials Project
YRh2Si crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Y sites. In the first Y site, Y is bonded in a 9-coordinate geometry to one Y and nine equivalent Rh atoms. The Y–Y bond length is 3.23 Å. There are three shorter (3.01 Å) and six longer (3.12 Å) Y–Rh bond lengths. In the second Y site, Y is bonded in a 6-coordinate geometry to two equivalent Y, twelve equivalent Rh, and six Si atoms. All Y–Rh bond lengths are 3.32 Å. All Y–Si bond lengths are 3.21 Å. Rh is bonded in a 12-coordinate geometry to five Y, four equivalent Rh, and three Si atoms. All Rh–Rh bond lengths are 2.78 Å. There are two shorter (2.42 Å) and one longer (2.55 Å) Rh–Si bond lengths. There are three inequivalent Si sites. In the first Si site, Si is bonded in a 9-coordinate geometry to three equivalent Y and six equivalent 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 equivalent Rh atoms.
