Materials Data on La2Sn5Rh3 by Materials Project
La2Rh3Sn5 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional. La is bonded in a 2-coordinate geometry to one Rh and eight Sn atoms. The La–Rh bond length is 3.35 Å. There are a spread of La–Sn bond distances ranging from 3.23–3.58 Å. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 6-coordinate geometry to six Sn atoms. There are four shorter (2.70 Å) and two longer (2.89 Å) Rh–Sn bond lengths. In the second Rh site, Rh is bonded in a 5-coordinate geometry to one La and five Sn atoms. There are a spread of Rh–Sn bond distances ranging from 2.60–2.71 Å. There are three inequivalent Sn sites. In the first Sn site, Sn is bonded in a 4-coordinate geometry to four equivalent La, three Rh, and two equivalent Sn atoms. Both Sn–Sn bond lengths are 3.01 Å. In the second Sn site, Sn is bonded in a 4-coordinate geometry to four equivalent Rh atoms. In the third Sn site, Sn is bonded in a 2-coordinate geometry to four equivalent La, three Rh, and four Sn atoms. Both Sn–Sn bond lengths are 3.24 Å.
