Materials Data on La2Ge5Rh3 by Materials Project

Abstract

La2Rh3Ge5 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional. La is bonded in a 1-coordinate geometry to seven Rh and ten Ge atoms. There are a spread of La–Rh bond distances ranging from 3.24–3.58 Å. There are a spread of La–Ge bond distances ranging from 3.08–3.36 Å. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 5-coordinate geometry to five equivalent La and five Ge atoms. There are a spread of Rh–Ge bond distances ranging from 2.46–2.55 Å. In the second Rh site, Rh is bonded in a 6-coordinate geometry to four equivalent La and six Ge atoms. There are four shorter (2.54 Å) and two longer (2.76 Å) Rh–Ge bond lengths. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 8-coordinate geometry to four equivalent La and four equivalent Rh atoms. In the second Ge site, Ge is bonded in a 2-coordinate geometry to four equivalent La, three Rh, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.70 Å. In the third Ge site, Ge is bonded in a 9-coordinate geometry to four equivalent La, three Rh, and two equivalent Ge atoms.
