The structure described by Er2CoGe2 crystallizes in the monoclinic C2/m space group. There are two inequivalent Er sites. In the first Er site, Er(1) is bonded in a 8-coordinate geometry to two equivalent Co(1), one Ge(2), and five equivalent Ge(1) atoms. In the second Er site, Er(2) is bonded in a 11-coordinate geometry to four equivalent Co(1), two equivalent Ge(1), and five equivalent Ge(2) atoms. Co(1) is bonded in a 10-coordinate geometry to two equivalent Er(1), four equivalent Er(2), one Ge(1), and three equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Er(2), five equivalent Er(1), one Co(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 10-coordinate geometry to one Er(1), five equivalent Er(2), three equivalent Co(1), and one Ge(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
