Materials Data on SbTe8Cl6O6F31 by Materials Project
SbTe6(OF5)6Te2Cl6F crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one SbTe6(OF5)6 cluster and one Te2Cl6F cluster. In the SbTe6(OF5)6 cluster, 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 39–40°.

In the third Te+5.50+ site, Te+5.50+ 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 40°. 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. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sb5+ and one Te+5.50+ atom.
