Materials Data on ErFe2 by Materials Project
ErFe2 is Cubic Laves structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Er is bonded in a 12-coordinate geometry to twelve equivalent Fe atoms. All Er–Fe bond lengths are 2.99 Å. Fe is bonded to six equivalent Er and six equivalent Fe atoms to form a mixture of face, edge, and corner-sharing FeEr6Fe6 cuboctahedra. All Fe–Fe bond lengths are 2.55 Å.
