Materials Data on KTeO4 by Materials Project

Abstract

KTeO4 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. K is bonded to six O atoms to form distorted KO6 octahedra that share corners with eight equivalent TeO6 octahedra and edges with two equivalent KO6 octahedra. The corner-sharing octahedra tilt angles range from 48–61°. There are a spread of K–O bond distances ranging from 2.68–2.91 Å. Te is bonded to six O atoms to form TeO6 octahedra that share corners with eight equivalent KO6 octahedra and edges with two equivalent TeO6 octahedra. The corner-sharing octahedra tilt angles range from 48–61°. There are a spread of Te–O bond distances ranging from 1.89–2.03 Å. There are two inequivalent O sites. In the first O site, O is bonded in a distorted trigonal planar geometry to one K and two equivalent Te atoms. In the second O site, O is bonded in a 3-coordinate geometry to two equivalent K and one Te atom.
