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.
