There are five inequivalent Rh sites. In the first Rh site, Rh(4) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Si(2) atoms. In the second Rh site, Rh(5) is bonded in a 4-coordinate geometry to two equivalent Er(1), one Si(3), and three equivalent Si(2) atoms. In the third Rh site, Rh(1) is bonded in a 4-coordinate geometry to two equivalent Er(1), one Si(1), and three equivalent Si(3) atoms. In the fourth Rh site, Rh(2) is bonded in a 6-coordinate geometry to two equivalent Er(1), one Si(1), one Si(2), and two equivalent Si(3) atoms. In the fifth Rh site, Rh(3) is bonded in a 5-coordinate geometry to one Si(3) and four equivalent Si(1) atoms. There are three inequivalent Si sites. In the first Si site, Si(1) is bonded in a 6-coordinate geometry to two equivalent Er(1), one Rh(1), one Rh(2), and four equivalent Rh(3) atoms. In the second Si site, Si(2) is bonded in a 9-coordinate geometry to two equivalent Er(1), one Rh(2), three equivalent Rh(4), and three equivalent Rh(5) atoms.
