Materials Data on FeCo2Ge by Materials Project

Co2FeGe is Heusler structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Fe is bonded in a distorted body-centered cubic geometry to eight equivalent Co and six equivalent Ge atoms. All Fe–Co bond lengths are 2.48 Å. All Fe–Ge bond lengths are 2.86 Å. Co is bonded in a body-centered cubic geometry to four equivalent Fe and four equivalent Ge atoms. All Co–Ge bond lengths are 2.48 Å. Ge is bonded in a distorted body-centered cubic geometry to six equivalent Fe and eight equivalent Co atoms.

Materials Data on FeCoGe by Materials Project

CoFeGe crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Fe is bonded in a 6-coordinate geometry to two equivalent Fe, six equivalent Co, and six equivalent Ge atoms. Both Fe–Fe bond lengths are 2.52 Å. All Fe–Co bond lengths are 2.67 Å. All Fe–Ge bond lengths are 2.67 Å. Co is bonded in a 5-coordinate geometry to six equivalent Fe and five equivalent Ge atoms. There are three shorter (2.35 Å) and two longer (2.52 Å) Co–Ge bond lengths. Ge is bonded in a 11-coordinate geometry to six equivalent Fe and five equivalent Co atoms.
