The compound described by ErCo2 is Cubic Laves structured and crystallizes in the cubic Fd-3m space group. Er(1) is bonded in a 12-coordinate geometry to twelve equivalent Co(1) atoms. Co(1) is bonded to six equivalent Er(1) and six equivalent Co(1) atoms to form a mixture of face, corner, and edge-sharing CoEr6Co6 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
