The compound described by Er7Rh3 crystallizes in the hexagonal P6_3mc space group. There are three inequivalent Er sites. In the first Er site, Er(1) is bonded in a 3-coordinate geometry to three equivalent Rh(1) atoms. In the second Er site, Er(2) is bonded in a distorted water-like geometry to two equivalent Rh(1) atoms. In the third Er site, Er(3) is bonded in a 3-coordinate geometry to three equivalent Rh(1) atoms. Rh(1) is bonded in a 6-coordinate geometry to one Er(3), two equivalent Er(2), and three equivalent Er(1) atoms. is represented by the CIF file [CIF]
