The crystal structure described by Er3Ru2 crystallizes in the hexagonal P6_3/m space group. Er(1) is bonded in a 5-coordinate geometry to two equivalent Ru(2) and three equivalent Ru(1) atoms. There are two inequivalent Ru sites. In the first Ru site, Ru(2) is bonded in a body-centered cubic geometry to six equivalent Er(1) and two equivalent Ru(2) atoms. In the second Ru site, Ru(1) is bonded in a 9-coordinate geometry to nine equivalent Er(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
