Materials Data on Cs2Te2O5 by Materials Project

Cs2Te2O5 crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. there are two inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Cs–O bond distances ranging from 3.17–3.62 Å. In the second Cs1+ site, Cs1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Cs–O bond distances ranging from 3.12–3.41 Å. There are two inequivalent Te4+ sites. In the first Te4+ site, Te4+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are a spread of Te–O bond distances ranging from 1.86–2.68 Å. In the second Te4+ site, Te4+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are a spread of Te–O bond distances ranging from 1.86–2.72 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to four Cs1+ and one Te4+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two Cs1+ and two Te4+ atoms. In the third O2- site, O2- is bonded in a distorted single-bond geometry to four Cs1+ and two Te4+ atoms. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to four Cs1+ and one Te4+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to four Cs1+ and two Te4+ atoms.
