Materials Data on Cs4FeO3 by Materials Project
Cs4FeO3 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are four inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Cs–O bond distances ranging from 2.89–3.36 Å. In the second Cs1+ site, Cs1+ is bonded to four O2- atoms to form distorted edge-sharing CsO4 trigonal pyramids. There are a spread of Cs–O bond distances ranging from 2.95–3.36 Å. In the third Cs1+ site, Cs1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Cs–O bond distances ranging from 3.06–3.47 Å. In the fourth Cs1+ site, Cs1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Cs–O bond distances ranging from 2.99–3.52 Å. Fe2+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of Fe–O bond distances ranging from 1.90–1.94 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to five Cs1+ and one Fe2+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to five Cs1+ and one Fe2+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to six Cs1+ and one Fe2+ atom.
