Materials Data on ErGeRh by Materials Project

ErRhGe crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Er is bonded in a 11-coordinate geometry to six equivalent Rh and five equivalent Ge atoms. There are a spread of Er–Rh bond distances ranging from 3.00–3.33 Å. There are three shorter (3.00 Å) and two longer (3.01 Å) Er–Ge bond lengths. Rh is bonded in a 10-coordinate geometry to six equivalent Er and four equivalent Ge atoms. There are a spread of Rh–Ge bond distances ranging from 2.55–2.62 Å. Ge is bonded in a 9-coordinate geometry to five equivalent Er and four equivalent Rh atoms.
