The crystal structure described by Er2Mg crystallizes in the orthorhombic Fmmm space group. Mg(1) is bonded to four equivalent Mg(1) and eight equivalent Er(1) atoms to form a mixture of distorted face and corner-sharing MgEr8Mg4 cuboctahedra. Er(1) is bonded in a 8-coordinate geometry to four equivalent Mg(1) and six equivalent Er(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
