Materials Data on NiTeO3 by Materials Project
NiTeO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Ni2+ is bonded to four O2- atoms to form distorted NiO4 trigonal pyramids that share corners with eight equivalent TeO6 octahedra and corners with two equivalent NiO4 trigonal pyramids. The corner-sharing octahedra tilt angles range from 60–83°. There are a spread of Ni–O bond distances ranging from 2.01–2.17 Å. Te4+ is bonded to six O2- atoms to form TeO6 octahedra that share corners with six equivalent TeO6 octahedra and corners with eight equivalent NiO4 trigonal pyramids. The corner-sharing octahedra tilt angles range from 50–53°. There are a spread of Te–O bond distances ranging from 2.16–2.28 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to one Ni2+ and two equivalent Te4+ atoms. In the second O2- site, O2- is bonded to two equivalent Ni2+ and two equivalent Te4+ atoms to form distorted corner-sharing ONi2Te2 trigonal pyramids.
