The compound described by Ho3Si2(Rh3Sn)3 crystallizes in the hexagonal P-62m space group. Ho(1) is bonded in a 12-coordinate geometry to two equivalent Rh(2), eight equivalent Rh(1), and two equivalent Si(1) atoms. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 8-coordinate geometry to four equivalent Ho(1), two equivalent Sn(1), and two equivalent Si(1) atoms. In the second Rh site, Rh(2) is bonded in a 6-coordinate geometry to two equivalent Ho(1) and four equivalent Sn(1) atoms. Sn(1) is bonded in a distorted body-centered cubic geometry to four equivalent Rh(1) and four equivalent Rh(2) atoms. Si(1) is bonded in a 9-coordinate geometry to three equivalent Ho(1) and six equivalent Rh(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
