Materials Data on La3Ge5 by Materials Project
La3Ge5 crystallizes in the orthorhombic Fdd2 space group. The structure is three-dimensional. there are two inequivalent La sites. In the first La site, La is bonded in a 10-coordinate geometry to ten Ge atoms. There are a spread of La–Ge bond distances ranging from 3.13–3.54 Å. In the second La site, La is bonded in a 10-coordinate geometry to ten Ge atoms. There are a spread of La–Ge bond distances ranging from 3.19–3.54 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 8-coordinate geometry to six La and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.63 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to six La and three Ge atoms. There are one shorter (2.57 Å) and one longer (2.69 Å) Ge–Ge bond lengths. In the third Ge site, Ge is bonded in a 8-coordinate geometry to six La and two equivalent Ge atoms.
