Materials Data on Sb2Te2O9 by Materials Project
Abstract
Sb2Te2O9 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are four inequivalent Sb5+ sites. In the first Sb5+ site, Sb5+ is bonded to six O2- atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedral tilt angles are 45°. There are a spread of Sb–O bond distances ranging from 1.97–2.07 Å. In the second Sb5+ site, Sb5+ is bonded to six O2- atoms to form corner-sharing SbO6 octahedra. There are a spread of Sb–O bond distances ranging from 1.98–2.04 Å. In the third Sb5+ site, Sb5+ is bonded to six O2- atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedra tilt angles range from 44–45°. There are a spread of Sb–O bond distances ranging from 1.98–2.06 Å. In the fourth Sb5+ site, Sb5+ is bonded to five O2- atoms to form SbO5 trigonal bipyramids that share a cornercorner with one SbO6 octahedra and corners with two equivalent SbO5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 45°. There are a spread of Sb–O bond distances ranging from 1.93–2.00 Å. There are four 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 spreadmore »
