Materials Data on Y3(SiRh)2 by Materials Project
Y3(RhSi)2 crystallizes in the orthorhombic Pbcm space group. The structure is three-dimensional. there are two inequivalent Y sites. In the first Y site, Y is bonded in a 6-coordinate geometry to four equivalent Rh and five Si atoms. There are a spread of Y–Rh bond distances ranging from 2.90–3.10 Å. There are a spread of Y–Si bond distances ranging from 2.96–3.40 Å. In the second Y site, Y is bonded in a 9-coordinate geometry to four equivalent Rh and five Si atoms. There are two shorter (3.02 Å) and two longer (3.10 Å) Y–Rh bond lengths. There are a spread of Y–Si bond distances ranging from 2.97–3.28 Å. Rh is bonded in a 9-coordinate geometry to six Y and three Si atoms. There are a spread of Rh–Si bond distances ranging from 2.49–2.52 Å. There are two inequivalent Si sites. In the first Si site, Si is bonded in a 9-coordinate geometry to seven Y and two equivalent Rh atoms. In the second Si site, Si is bonded in a 12-coordinate geometry to eight Y and four equivalent Rh atoms.
