Materials Data on Er5Ge3 by Materials Project
Er5Ge3 crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. there are two inequivalent Er sites. In the first Er site, Er is bonded in a 5-coordinate geometry to five equivalent Ge atoms. There are a spread of Er–Ge bond distances ranging from 2.90–3.42 Å. In the second Er site, Er is bonded in a 6-coordinate geometry to six equivalent Ge atoms. All Er–Ge bond lengths are 3.04 Å. Ge is bonded in a 9-coordinate geometry to nine Er atoms.
