The structure described by Fe7Co 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) atoms. In the second Fe site, Fe(2) is bonded in a distorted body-centered cubic geometry to six equivalent Fe(1) and two equivalent Co(1) atoms. Co(1) is bonded in a distorted body-centered cubic geometry to eight equivalent Fe(2) atoms. is represented by the CIF card [CIF]
