Materials Data on Fe3Sb(PO4)6 by Materials Project
Fe3Sb(PO4)6 crystallizes in the trigonal R3 space group. The structure is three-dimensional. there are three inequivalent Fe sites. In the first Fe site, Fe is bonded to six O atoms to form FeO6 octahedra that share corners with six PO4 tetrahedra. All Fe–O bond lengths are 1.99 Å. In the second Fe site, Fe is bonded to six O atoms to form FeO6 octahedra that share corners with six PO4 tetrahedra. All Fe–O bond lengths are 1.99 Å. In the third Fe site, Fe is bonded to six O atoms to form FeO6 octahedra that share corners with six PO4 tetrahedra. All Fe–O bond lengths are 1.99 Å. Sb is bonded to six O atoms to form SbO6 octahedra that share corners with six PO4 tetrahedra. All Sb–O bond lengths are 1.98 Å. There are two inequivalent P sites. In the first P site, P is bonded to four O atoms to form PO4 tetrahedra that share a cornercorner with one SbO6 octahedra and corners with three FeO6 octahedra. The corner-sharing octahedra tilt angles range from 25–31°. There is three shorter (1.53 Å) and one longer (1.57 Å) P–O bond length. In the second P site, P is bonded to four O atoms to form PO4 tetrahedra that share a cornercorner with one SbO6 octahedra and corners with three FeO6 octahedra. The corner-sharing octahedra tilt angles range from 26–33°. There is three shorter (1.53 Å) and one longer (1.57 Å) P–O bond length. There are eight inequivalent O sites. In the first O site, O is bonded in a bent 150 degrees geometry to one Fe and one P atom. In the second O site, O is bonded in a bent 150 degrees geometry to one Fe and one P atom. In the third O site, O is bonded in a bent 150 degrees geometry to one Sb and one P atom. In the fourth O site, O is bonded in a bent 150 degrees geometry to one Fe and one P atom. In the fifth O site, O is bonded in a bent 150 degrees geometry to one Sb and one P atom. In the sixth O site, O is bonded in a bent 150 degrees geometry to one Fe and one P atom. In the seventh O site, O is bonded in a bent 150 degrees geometry to one Fe and one P atom. In the eighth O site, O is bonded in a bent 150 degrees geometry to one Fe and one P atom.
