Materials Data on Y2Si2Rh by Materials Project
Y2RhSi2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Y sites. In the first Y site, Y is bonded in a 2-coordinate geometry to four equivalent Rh and six Si atoms. There are a spread of Y–Rh bond distances ranging from 3.06–3.15 Å. There are a spread of Y–Si bond distances ranging from 2.92–3.07 Å. In the second Y site, Y is bonded in a 6-coordinate geometry to two equivalent Rh and six Si atoms. Both Y–Rh bond lengths are 3.26 Å. There are a spread of Y–Si bond distances ranging from 2.90–3.16 Å. Rh is bonded in a 4-coordinate geometry to six Y and four Si atoms. There are a spread of Rh–Si bond distances ranging from 2.45–2.59 Å. There are two inequivalent Si sites. In the first Si site, Si is bonded in a 9-coordinate geometry to five Y, three equivalent Rh, and one Si atom. The Si–Si bond length is 2.62 Å. In the second Si site, Si is bonded in a 9-coordinate geometry to seven Y, one Rh, and one Si atom. The Si–Si bond length is 2.56 Å.
