The material described by Fe9Co7 is Tungsten-derived structured and crystallizes in the cubic Pm-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 one Fe(2), one Co(3), three equivalent Co(1), and three equivalent Co(2) atoms. In the second Fe site, Fe(2) is bonded in a distorted body-centered cubic geometry to eight equivalent Fe(1) and six equivalent Co(2) atoms. There are three inequivalent Co sites. In the first Co site, Co(1) is bonded in a body-centered cubic geometry to eight equivalent Fe(1) atoms. In the second Co site, Co(2) is bonded in a distorted body-centered cubic geometry to two equivalent Fe(2) and eight equivalent Fe(1) atoms. In the third Co site, Co(3) is bonded in a body-centered cubic geometry to eight equivalent Fe(1) atoms. is represented by the CIF card [CIF]
