title: Materials Data on CsSbTe6(OF5)6 by Materials Project

description: CsSbTe6(OF5)6 crystallizes in the tetragonal P4_2/n space group. The structure is three-dimensional. Cs1+ is bonded in a 10-coordinate geometry to ten F1- atoms. There are a spread of Cs–F bond distances ranging from 2.98–3.52 Å. Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with six TeOF5 octahedra. The corner-sharing octahedra tilt angles range from 36–38°. There is four shorter (1.99 Å) and two longer (2.00 Å) Sb–O bond length. There are three inequivalent Te6+ sites. In the first Te6+ site, Te6+ is bonded to one O2- and five F1- atoms to form TeOF5 octahedra that share a cornercorner with one SbO6 octahedra. The corner-sharing octahedral tilt angles are 38°. The Te–O bond length is 1.89 Å. There are a spread of Te–F bond distances ranging from 1.87–1.89 Å. In the second Te6+ site, Te6+ is bonded to one O2- and five F1- atoms to form TeOF5 octahedra that share a cornercorner with one SbO6 octahedra. The corner-sharing octahedral tilt angles are 36°. The Te–O bond length is 1.87 Å. There are a spread of Te–F bond distances ranging from 1.87–1.89 Å. In the third Te6+ site, Te6+ is bonded to one O2- and five F1- atoms to form TeOF5 octahedra that share a cornercorner with one SbO6 octahedra. The corner-sharing octahedral tilt angles are 38°. The Te–O bond length is 1.89 Å. There are a spread of Te–F bond distances ranging from 1.87–1.90 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Sb5+ and one Te6+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sb5+ and one Te6+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sb5+ and one Te6+ atom. There are fifteen inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Te6+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Te6+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one Te6+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one Te6+ atom. In the fifth F1- site, F1- is bonded in a distorted single-bond geometry to one Cs1+ and one Te6+ atom. In the sixth F1- site, F1- is bonded in a distorted single-bond geometry to one Cs1+ and one Te6+ atom. In the seventh F1- site, F1- is bonded in a distorted single-bond geometry to one Cs1+ and one Te6+ atom. In the eighth F1- site, F1- is bonded in a single-bond geometry to one Cs1+ and one Te6+ atom. In the ninth F1- site, F1- is bonded in a single-bond geometry to one Te6+ atom. In the tenth F1- site, F1- is bonded in a single-bond geometry to one Te6+ atom. In the eleventh F1- site, F1- is bonded in a single-bond geometry to one Te6+ atom. In the twelfth F1- site, F1- is bonded in a single-bond geometry to one Te6+ atom. In the thirteenth F1- site, F1- is bonded in a single-bond geometry to one Te6+ atom. In the fourteenth F1- site, F1- is bonded in a single-bond geometry to one Te6+ atom. In the fifteenth F1- site, F1- is bonded in a single-bond geometry to one Cs1+ and one Te6+ atom.
