The material structure described by SmYFe4 is Cubic Laves-derived structured and crystallizes in the cubic F-43m space group. Sm(1) is bonded in a 16-coordinate geometry to four equivalent Y(1) and twelve equivalent Fe(1) atoms. Y(1) is bonded in a 16-coordinate geometry to four equivalent Sm(1) and twelve equivalent Fe(1) atoms. Fe(1) is bonded to three equivalent Sm(1), three equivalent Y(1), and six equivalent Fe(1) atoms to form a mixture of corner, face, and edge-sharing FeSm3Y3Fe6 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
