Materials Data on Y2Si5Rh3 by Materials Project

Abstract

Y2Rh3Si5 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Y is bonded in a 5-coordinate geometry to seven Rh and ten Si atoms. There are a spread of Y–Rh bond distances ranging from 3.09–3.49 Å. There are a spread of Y–Si bond distances ranging from 2.99–3.33 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 six Si atoms. There are a spread of Rh–Si bond distances ranging from 2.44–2.68 Å. In the second Rh site, Rh is bonded in a 5-coordinate geometry to five equivalent Y and five Si atoms. There are a spread of Rh–Si bond distances ranging from 2.37–2.49 Å. There are four inequivalent Si sites. In the first Si site, Si is bonded in a 2-coordinate geometry to four equivalent Y, three Rh, and two equivalent Si atoms. Both Si–Si bond lengths are 2.53 Å. In the second Si site, Si is bonded in a 4-coordinate geometry to four equivalent Y and four equivalent Rh atoms. In the third Si site, Si is bonded in a 3-coordinate geometry to four equivalent Y, three Rh, and two equivalent Si atoms. Both Si–Si bond lengths are 2.52 Å. In the fourth Si site, Si is bonded in a 9-coordinate geometry to four equivalent Y, three Rh, and two Si atoms.
