The material described by Er2Rh3Si5 crystallizes in the orthorhombic Ibam space group. Er(1) is bonded in a 17-coordinate geometry to two equivalent Rh(2), five equivalent Rh(1), two equivalent Si(3), four equivalent Si(1), and four equivalent Si(2) atoms. There are two inequivalent Rh sites. In the first Rh site, Rh(2) is bonded in a 6-coordinate geometry to four equivalent Er(1), two equivalent Si(1), and four equivalent Si(2) atoms. In the second Rh site, Rh(1) is bonded in a 5-coordinate geometry to five equivalent Er(1), one Si(2), two equivalent Si(1), and two equivalent Si(3) atoms. There are three inequivalent Si sites. In the first Si site, Si(1) is bonded in a 3-coordinate geometry to four equivalent Er(1), one Rh(2), two equivalent Rh(1), and two equivalent Si(2) atoms. In the second Si site, Si(2) is bonded in a 9-coordinate geometry to four equivalent Er(1), one Rh(1), two equivalent Rh(2), and two equivalent Si(1) atoms. In the third Si site, Si(3) is bonded in a 4-coordinate geometry to four equivalent Er(1) and four equivalent Rh(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
