The compound described by Ho5Rh6Sn17Sn crystallizes in the cubic F-43m space group. The structure consists of four 7440-31-5 atoms inside a Ho5Rh6Sn17 framework. In the Ho5Rh6Sn17 framework, there are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 18-coordinate geometry to six equivalent Rh(1) and twelve equivalent Sn(3) atoms. In the second Ho site, Ho(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 Ho(1), two equivalent Ho(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 Ho(2) atoms. In the second Sn site, Sn(1) is bonded in a hexagonal planar geometry to three equivalent Ho(2) and three equivalent Rh(1) atoms. In the third Sn site, Sn(3) is bonded in a 2-coordinate geometry to one Ho(1), two equivalent Ho(2), and two equivalent Rh(1) atoms. is represented by the CIF file [CIF]
