The structure described by Er2Ru3Si5 crystallizes in the orthorhombic Ibam space group. Er(1) is bonded in a 16-coordinate geometry to two equivalent Ru(2), four equivalent Ru(1), two equivalent Si(1), four equivalent Si(2), and four equivalent Si(3) atoms. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 9-coordinate geometry to four equivalent Er(1), one Si(3), two equivalent Si(1), and two equivalent Si(2) atoms. In the second Ru site, Ru(2) is bonded in a 6-coordinate geometry to four equivalent Er(1), two equivalent Si(2), and four equivalent Si(3) atoms. There are three inequivalent Si sites. In the first Si site, Si(1) is bonded in a 4-coordinate geometry to four equivalent Er(1) and four equivalent Ru(1) atoms. In the second Si site, Si(2) is bonded in a 11-coordinate geometry to four equivalent Er(1), one Ru(2), two equivalent Ru(1), two equivalent Si(2), and two equivalent Si(3) atoms. In the third Si site, Si(3) is bonded in a 9-coordinate geometry to four equivalent Er(1), one Ru(1), two equivalent Ru(2), and two equivalent Si(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
