Materials Data on Fe3N by Materials Project

Abstract

Fe3N is Upper Bainite-like structured and crystallizes in the trigonal P312 space group. The structure is three-dimensional. there are four inequivalent Fe sites. In the first Fe site, Fe is bonded in a bent 120 degrees geometry to two N atoms. Both Fe–N bond lengths are 1.90 Å. In the second Fe site, Fe is bonded in a bent 120 degrees geometry to two N atoms. Both Fe–N bond lengths are 1.90 Å. In the third Fe site, Fe is bonded in a bent 120 degrees geometry to two N atoms. Both Fe–N bond lengths are 1.91 Å. In the fourth Fe site, Fe is bonded in a bent 120 degrees geometry to two N atoms. Both Fe–N bond lengths are 1.90 Å. There are five inequivalent N sites. In the first N site, N is bonded to six Fe atoms to form corner-sharing NFe6 octahedra. The corner-sharing octahedral tilt angles are 50°. In the second N site, N is bonded to six equivalent Fe atoms to form corner-sharing NFe6 octahedra. The corner-sharing octahedral tilt angles are 50°. In the third N site, N is bonded to six equivalent Fe atoms to form corner-sharing NFe6 octahedra. The corner-sharing octahedral tilt angles are 50°. In the fourth N site, N is bonded to six Fe atoms to form corner-sharing NFe6 octahedra. The corner-sharing octahedral tilt angles are 50°. In the fifth N site, N is bonded to six Fe atoms to form corner-sharing NFe6 octahedra. The corner-sharing octahedral tilt angles are 50°.
