Title: Materials Data on CsAlFe3(SiO4)3 by Materials Project

Abstract

CsFe3Al(SiO4)3 crystallizes in the triclinic P1 space group. The structure is three-dimensional. Cs1+ is bonded to twelve O2- atoms to form distorted CsO12 cuboctahedra that share edges with six equivalent CsO12 cuboctahedra, edges with three equivalent AlO4 tetrahedra, and edges with nine SiO4 tetrahedra. There are a spread of Cs–O bond distances ranging from 3.10–3.55 Å. There are three inequivalent Fe+2.67+ sites. In the first Fe+2.67+ site, Fe+2.67+ is bonded to six O2- atoms to form FeO6 octahedra that share a cornercorner with one AlO4 tetrahedra, corners with three SiO4 tetrahedra, and edges with six FeO6 octahedra. There are a spread of Fe–O bond distances ranging from 2.04–2.29 Å.

In the second O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to three Fe+2.67+ and one Si4+ atom. In the third O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to three Fe+2.67+ and one Si4+ atom. In the fourth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to three Fe+2.67+ and one Si4+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Cs1+, one Al3+, and one Si4+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Cs1+ and two Si4+ atoms. In the seventh O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to three Fe+2.67+ atoms. In the eighth O2- site, O2- is bonded in a distorted T-shaped geometry to three Fe+2.67+ atoms. In the ninth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Cs1+, one Al3+, and one Si4+ atom.
