Materials Data on ErBiRh by Materials Project
ErRhBi crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Er is bonded in a 11-coordinate geometry to five Rh and six equivalent Bi atoms. There are one shorter (3.06 Å) and four longer (3.07 Å) Er–Rh bond lengths. There are two shorter (3.24 Å) and four longer (3.35 Å) Er–Bi bond lengths. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 9-coordinate geometry to three equivalent Er and six equivalent Bi atoms. All Rh–Bi bond lengths are 2.84 Å. In the second Rh site, Rh is bonded in a 9-coordinate geometry to six equivalent Er and three equivalent Bi atoms. All Rh–Bi bond lengths are 2.85 Å. Bi is bonded in a 10-coordinate geometry to six equivalent Er and four Rh atoms.
