Abstract
CaTeO3 crystallizes in the tetragonal P4_3 space group. The structure is three-dimensional. there are five inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded to six O2- atoms to form distorted corner-sharing CaO6 octahedra. There are a spread of Ca–O bond distances ranging from 2.27–2.43 Å. In the second Ca2+ site, Ca2+ is bonded in a 8-coordinate geometry to seven O2- atoms. There are a spread of Ca–O bond distances ranging from 2.38–2.84 Å. In the third Ca2+ site, Ca2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ca–O bond distances ranging from 2.34–2.87 Å. In the fourth Ca2+ site, Ca2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ca–O bond distances ranging from 2.31–2.69 Å. In the fifth Ca2+ site, Ca2+ is bonded to seven O2- atoms to form distorted corner-sharing CaO7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 49°. There are a spread of Ca–O bond distances ranging from 2.42–2.47 Å. There are five inequivalent Te4+ sites. In the first Te4+ site, Te4+ is bonded in a 3-coordinate geometry to five O2- atoms. There are a spread of Te–O bond distancesmore »
