The crystal structure described by Er6FeSb2 crystallizes in the hexagonal P-62m space group. There are two inequivalent Er sites. In the first Er site, Er(1) is bonded in a 4-coordinate geometry to two equivalent Fe(1) and two equivalent Sb(1) atoms. In the second Er site, Er(2) is bonded in a 5-coordinate geometry to one Fe(1) and four equivalent Sb(1) atoms. Fe(1) is bonded in a 9-coordinate geometry to three equivalent Er(2) and six equivalent Er(1) atoms. Sb(1) is bonded in a 9-coordinate geometry to three equivalent Er(1) and six equivalent Er(2) atoms. is represented by the CIF file [CIF]
