Materials Data on Er3Rh by Materials Project
Er3Rh is Cementite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Er sites. In the first Er site, Er is bonded in a 2-coordinate geometry to three equivalent Rh atoms. There are a spread of Er–Rh bond distances ranging from 2.83–3.28 Å. In the second Er site, Er is bonded in a distorted bent 150 degrees geometry to two equivalent Rh atoms. There are one shorter (2.75 Å) and one longer (2.83 Å) Er–Rh bond lengths. Rh is bonded in a 6-coordinate geometry to eight Er atoms.
