The compound described by Er3Ru2Ge3 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Er sites. In the first Er site, Er(1) is bonded in a 10-coordinate geometry to four equivalent Ru(1), two equivalent Ge(2), and four equivalent Ge(1) atoms. In the second Er site, Er(2) is bonded in a 9-coordinate geometry to four equivalent Ru(1), two equivalent Ge(1), and three equivalent Ge(2) atoms. Ru(1) is bonded in a 10-coordinate geometry to two equivalent Er(2), four equivalent Er(1), one Ge(2), and three equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to one Er(2), four equivalent Er(1), three equivalent Ru(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to three equivalent Er(2), four equivalent Er(1), and two equivalent Ru(1) atoms. is represented by the CIF file [CIF]
