Materials Data on NiTeO4 by Materials Project

NiTeO4 is Hydrophilite-derived structured and crystallizes in the monoclinic Pc space group. The structure is three-dimensional. Ni4+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with four equivalent NiO6 octahedra, corners with four equivalent TeO6 octahedra, and edges with two equivalent TeO6 octahedra. The corner-sharing octahedra tilt angles range from 47–56°. There are a spread of Ni–O bond distances ranging from 2.05–2.13 Å. Te4+ is bonded to six O2- atoms to form TeO6 octahedra that share corners with four equivalent NiO6 octahedra, corners with four equivalent TeO6 octahedra, and edges with two equivalent NiO6 octahedra. The corner-sharing octahedra tilt angles range from 47–52°. There are a spread of Te–O bond distances ranging from 1.88–2.01 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Ni4+ and one Te4+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Ni4+ and two equivalent Te4+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Ni4+ and one Te4+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Ni4+ and two equivalent Te4+ atoms.
