Fe5Co3 is Tungsten-derived structured and crystallizes in the cubic Im-3m space group. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a distorted body-centered cubic geometry to eight equivalent Fe(2) and six equivalent Co(1) atoms. In the second Fe site, Fe(2) is bonded in a distorted body-centered cubic geometry to two equivalent Fe(1) and six equivalent Co(1) atoms. Co(1) is bonded in a distorted body-centered cubic geometry to two equivalent Fe(1) and eight equivalent Fe(2) atoms.
