Materials Data on Fe3Se3O10 by Materials Project
Fe3Se3O10 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are four inequivalent Fe+2.67+ sites. In the first Fe+2.67+ site, Fe+2.67+ is bonded to six O2- atoms to form a mixture of distorted edge and corner-sharing FeO6 octahedra. The corner-sharing octahedra tilt angles range from 46–63°. There are a spread of Fe–O bond distances ranging from 1.66–2.15 Å. In the second Fe+2.67+ site, Fe+2.67+ is bonded to six O2- atoms to form a mixture of distorted edge and corner-sharing FeO6 octahedra. The corner-sharing octahedra tilt angles range from 54–63°. There are a spread of Fe–O bond distances ranging from 2.01–2.40 Å. In the third Fe+2.67+ site, Fe+2.67+ is bonded to six O2- atoms to form corner-sharing FeO6 octahedra. The corner-sharing octahedra tilt angles range from 46–54°. There are a spread of Fe–O bond distances ranging from 2.10–2.28 Å. In the fourth Fe+2.67+ site, Fe+2.67+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing FeO6 octahedra. The corner-sharing octahedral tilt angles are 54°. There are a spread of Fe–O bond distances ranging from 2.15–2.20 Å. There are three inequivalent Se4+ sites. In the first Se4+ site, Se4+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.72–1.78 Å. In the second Se4+ site, Se4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.69–1.77 Å. In the third Se4+ site, Se4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.69–1.81 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to two Fe+2.67+ and one Se4+ atom. In the second O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two equivalent Fe+2.67+ and one Se4+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two Fe+2.67+ and one Se4+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two Fe+2.67+ and one Se4+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Fe+2.67+ and one Se4+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Fe+2.67+ and one Se4+ atom. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to one Fe+2.67+ and one Se4+ atom. In the eighth O2- site, O2- is bonded in a single-bond geometry to one Fe+2.67+ atom. In the ninth O2- site, O2- is bonded in a bent 150 degrees geometry to one Fe+2.67+ and one Se4+ atom. In the tenth O2- site, O2- is bonded in a rectangular see-saw-like geometry to three Fe+2.67+ and one Se4+ atom.
