Materials Data on Fe4(PO4)3 by Materials Project
Fe4(PO4)3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Fe+2.25+ sites. In the first Fe+2.25+ site, Fe+2.25+ is bonded in a 4-coordinate geometry to six O2- atoms. There are a spread of Fe–O bond distances ranging from 1.98–2.76 Å. In the second Fe+2.25+ site, Fe+2.25+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Fe–O bond distances ranging from 2.03–2.67 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of P–O bond distances ranging from 1.53–1.59 Å. In the second P5+ site, P5+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of P–O bond distances ranging from 1.55–1.57 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two Fe+2.25+ and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two Fe+2.25+ and one P5+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to three Fe+2.25+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted T-shaped geometry to two equivalent Fe+2.25+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Fe+2.25+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Fe+2.25+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to one Fe+2.25+ and one P5+ atom.
