Materials Data on Er7Rh3 by Materials Project
Er7Rh3 crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. there are three inequivalent Er sites. In the first Er site, Er is bonded in a 3-coordinate geometry to three equivalent Rh atoms. There are two shorter (2.84 Å) and one longer (2.87 Å) Er–Rh bond lengths. In the second Er site, Er is bonded in a distorted water-like geometry to two equivalent Rh atoms. Both Er–Rh bond lengths are 2.80 Å. In the third Er site, Er is bonded in a 3-coordinate geometry to three equivalent Rh atoms. All Er–Rh bond lengths are 2.78 Å. Rh is bonded in a 6-coordinate geometry to six Er atoms.
