Materials Data on Er(BRh)4 by Materials Project

ErRh4B4 crystallizes in the tetragonal I4_1/acd space group. The structure is three-dimensional. Er is bonded in a 8-coordinate geometry to twelve equivalent Rh and twelve equivalent B atoms. There are a spread of Er–Rh bond distances ranging from 2.91–3.26 Å. There are a spread of Er–B bond distances ranging from 2.96–3.26 Å. Rh is bonded in a 5-coordinate geometry to three equivalent Er and five equivalent B atoms. There are a spread of Rh–B bond distances ranging from 2.18–2.27 Å. B is bonded in a 6-coordinate geometry to three equivalent Er, five equivalent Rh, and one B atom. The B–B bond length is 1.75 Å.
