The crystal structure described by Er3Fe2Ge3 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 Fe(1), two equivalent Ge(2), and five equivalent Ge(1) atoms. In the second Er site, Er(2) is bonded in a 9-coordinate geometry to four equivalent Fe(1), two equivalent Ge(1), and three equivalent Ge(2) atoms. Fe(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 10-coordinate geometry to one Er(2), five equivalent Er(1), three equivalent Fe(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 Fe(1) atoms. is represented by the CIF file [CIF]
