Materials Data on La5Ge3 by Materials Project
La5Ge3 crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. there are two inequivalent La sites. In the first La site, La is bonded to six equivalent Ge atoms to form a mixture of distorted face, edge, and corner-sharing LaGe6 octahedra. The corner-sharing octahedral tilt angles are 35°. All La–Ge bond lengths are 3.29 Å. In the second La site, La is bonded in a 5-coordinate geometry to five equivalent Ge atoms. There are a spread of La–Ge bond distances ranging from 3.11–3.68 Å. Ge is bonded in a 9-coordinate geometry to nine La atoms.
