The material structure described by Fe15Co is Tungsten-derived structured and crystallizes in the cubic Pm-3m space group. There are four inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a distorted body-centered cubic geometry to eight equivalent Fe(4) atoms. In the second Fe site, Fe(2) is bonded in a distorted body-centered cubic geometry to eight equivalent Fe(4) atoms. In the third Fe site, Fe(3) is bonded in a distorted body-centered cubic geometry to eight equivalent Fe(4) atoms. In the fourth Fe site, Fe(4) is bonded in a distorted body-centered cubic geometry to one Fe(1), three equivalent Fe(2), three equivalent Fe(3), and one Co(1) atom. Co(1) is bonded in a body-centered cubic geometry to eight equivalent Fe(4) atoms. is represented by the CIF file [CIF]
