The crystal structure described by Fe3O crystallizes in the hexagonal P6_3/mmc space group. Fe(1) is bonded in a 2-coordinate geometry to four equivalent O(1) atoms. O(1) is bonded to twelve equivalent Fe(1) atoms to form a mixture of corner and face-sharing OFe12 cuboctahedra. is represented by the CIF card [CIF]
