Materials Data on SbTe3O8 by Materials Project

SbTe3O8 crystallizes in the cubic Ia-3 space group. The structure is three-dimensional. Sb5+ is bonded in an octahedral geometry to six equivalent O2- atoms. All Sb–O bond lengths are 2.13 Å. Te+3.67+ is bonded in a distorted see-saw-like geometry to four O2- atoms. There are two shorter (1.92 Å) and two longer (2.17 Å) Te–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to three equivalent Te+3.67+ atoms. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Sb5+ and one Te+3.67+ atom.
