The material described by Sr3Fe crystallizes in the hexagonal P6_3/mmc space group. Sr(1) is bonded in a 4-coordinate geometry to four equivalent Fe(1) atoms. Fe(1) is bonded to twelve equivalent Sr(1) atoms to form a mixture of face and corner-sharing FeSr12 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
