Materials Data on KFeP by Materials Project
KFeP is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. K1+ is bonded in a 4-coordinate geometry to four equivalent Fe2+ and six equivalent P3- atoms. All K–Fe bond lengths are 2.77 Å. All K–P bond lengths are 3.20 Å. Fe2+ is bonded in a body-centered cubic geometry to four equivalent K1+ and four equivalent P3- atoms. All Fe–P bond lengths are 2.77 Å. P3- is bonded in a 10-coordinate geometry to six equivalent K1+ and four equivalent Fe2+ atoms.
