Materials Data on Fe4(PO4)3 by Materials Project
Abstract
Fe4(PO4)3 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are four inequivalent Fe+2.25+ sites. In the first 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 2.00–2.49 Å. In the second Fe+2.25+ site, Fe+2.25+ is bonded to six O2- atoms to form distorted FeO6 pentagonal pyramids that share corners with six PO4 tetrahedra and an edgeedge with one FeO6 octahedra. There are a spread of Fe–O bond distances ranging from 2.08–2.35 Å. In the third Fe+2.25+ site, Fe+2.25+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Fe–O bond distances ranging from 1.96–2.14 Å. In the fourth Fe+2.25+ site, Fe+2.25+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six PO4 tetrahedra and an edgeedge with one FeO6 pentagonal pyramid. There are a spread of Fe–O bond distances ranging from 1.93–2.10 Å. There are three inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent FeO6 octahedra and corners with two equivalent FeO6 pentagonal pyramids.more »
