Materials Data on Y2Sn5Rh3 by Materials Project
Y2Rh3Sn5 crystallizes in the orthorhombic Cmc2_1 space group. The structure is three-dimensional. there are two inequivalent Y sites. In the first Y site, Y is bonded in a 1-coordinate geometry to five Rh and eight Sn atoms. There are a spread of Y–Rh bond distances ranging from 2.87–3.37 Å. There are a spread of Y–Sn bond distances ranging from 3.16–3.41 Å. In the second Y site, Y is bonded in a 8-coordinate geometry to two equivalent Rh and six Sn atoms. Both Y–Rh bond lengths are 3.27 Å. There are four shorter (3.18 Å) and two longer (3.20 Å) Y–Sn bond lengths. There are three inequivalent Rh sites. In the first Rh site, Rh is bonded in a 9-coordinate geometry to three Y and six Sn atoms. There are a spread of Rh–Sn bond distances ranging from 2.68–2.90 Å. In the second Rh site, Rh is bonded in a 7-coordinate geometry to seven Sn atoms. There are a spread of Rh–Sn bond distances ranging from 2.73–2.81 Å. In the third Rh site, Rh is bonded in a 9-coordinate geometry to four equivalent Y and five Sn atoms. There are a spread of Rh–Sn bond distances ranging from 2.64–2.79 Å. There are five inequivalent Sn sites. In the first Sn site, Sn is bonded in a 6-coordinate geometry to two equivalent Y and four Rh atoms. In the second Sn site, Sn is bonded in a 3-coordinate geometry to four Y, three Rh, and one Sn atom. The Sn–Sn bond length is 3.16 Å. In the third Sn site, Sn is bonded in a 12-coordinate geometry to four equivalent Y and four Rh atoms. In the fourth Sn site, Sn is bonded in a 5-coordinate geometry to two equivalent Y, three equivalent Rh, and one Sn atom. In the fifth Sn site, Sn is bonded in a 4-coordinate geometry to two equivalent Y and four Rh atoms.
