Materials Data on FeCoSn4 by Materials Project
FeCoSn4 is Khatyrkite-derived structured and crystallizes in the tetragonal I422 space group. The structure is three-dimensional. Fe is bonded in a 10-coordinate geometry to two equivalent Co and eight equivalent Sn atoms. Both Fe–Co bond lengths are 2.73 Å. All Fe–Sn bond lengths are 2.74 Å. Co is bonded in a distorted q6 geometry to two equivalent Fe and eight equivalent Sn atoms. All Co–Sn bond lengths are 2.74 Å. Sn is bonded in a 4-coordinate geometry to two equivalent Fe and two equivalent Co atoms.
