Materials Data on Er6FeSb2 by Materials Project
Er6FeSb2 crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. there are two inequivalent Er sites. In the first Er site, Er is bonded in a 4-coordinate geometry to two equivalent Fe and two equivalent Sb atoms. Both Er–Fe bond lengths are 2.81 Å. Both Er–Sb bond lengths are 3.19 Å. In the second Er site, Er is bonded in a 5-coordinate geometry to one Fe and four equivalent Sb atoms. The Er–Fe bond length is 3.20 Å. All Er–Sb bond lengths are 3.24 Å. Fe is bonded in a 9-coordinate geometry to nine Er atoms. Sb is bonded in a 9-coordinate geometry to nine Er atoms.
