The material structure described by Er5Rh6Sn17Sn crystallizes in the cubic F-43m space group. The structure consists of four 7440-31-5 atoms inside a Er5Rh6Sn17 framework. In the Er5Rh6Sn17 framework, there are two inequivalent Er sites. In the first Er site, Er(1) is bonded in a 18-coordinate geometry to six equivalent Rh(1) and twelve equivalent Sn(3) atoms. In the second Er site, Er(2) is bonded in a 13-coordinate geometry to three equivalent Rh(1), one Sn(4), three equivalent Sn(1), and six equivalent Sn(3) atoms. Rh(1) is bonded in a 8-coordinate geometry to one Er(1), two equivalent Er(2), two equivalent Sn(1), and four equivalent Sn(3) atoms. There are three inequivalent Sn sites. In the first Sn site, Sn(4) is bonded in a tetrahedral geometry to four equivalent Er(2) atoms. In the second Sn site, Sn(1) is bonded in a distorted hexagonal planar geometry to three equivalent Er(2) and three equivalent Rh(1) atoms. In the third Sn site, Sn(3) is bonded in a 2-coordinate geometry to one Er(1), two equivalent Er(2), and two equivalent Rh(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
