Materials Data on CsNbO3 by Materials Project
CsNbO3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Cs–O bond distances ranging from 3.05–3.49 Å. In the second Cs1+ site, Cs1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Cs–O bond distances ranging from 2.96–3.46 Å. There are two inequivalent Nb5+ sites. In the first Nb5+ site, Nb5+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Nb–O bond distances ranging from 1.82–2.43 Å. In the second Nb5+ site, Nb5+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Nb–O bond distances ranging from 1.82–2.53 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to two Cs1+ and two Nb5+ atoms. In the second O2- site, O2- is bonded in a distorted single-bond geometry to four Cs1+ and one Nb5+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two Cs1+ and two Nb5+ atoms. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to three Cs1+ and one Nb5+ atom. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to two Cs1+ and two Nb5+ atoms. In the sixth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to four Nb5+ atoms.
