Materials Data on Fe9Co7 by Materials Project
Fe9Co7 is Tungsten-derived structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. there are two inequivalent Fe sites. In the first Fe site, Fe is bonded in a distorted body-centered cubic geometry to one Fe and seven Co atoms. The Fe–Fe bond length is 2.47 Å. All Fe–Co bond lengths are 2.47 Å. In the second Fe site, Fe is bonded in a distorted body-centered cubic geometry to eight equivalent Fe and six equivalent Co atoms. All Fe–Co bond lengths are 2.85 Å. There are three inequivalent Co sites. In the first Co site, Co is bonded in a body-centered cubic geometry to eight equivalent Fe atoms. In the second Co site, Co is bonded in a distorted body-centered cubic geometry to ten Fe atoms. In the third Co site, Co is bonded in a body-centered cubic geometry to eight equivalent Fe atoms.
