Title: Materials Data on K2CuTeO7 by Materials Project

Abstract

K2CuTeO7 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. K is bonded in a 7-coordinate geometry to seven O atoms. There are a spread of K–O bond distances ranging from 2.77–3.17 Å. Cu is bonded in a square co-planar geometry to four O atoms. There is two shorter (1.85 Å) and two longer (1.86 Å) Cu–O bond length. Te is bonded in an octahedral geometry to six O atoms. There are a spread of Te–O bond distances ranging from 1.93–1.99 Å. There are four inequivalent O sites. In the first O site, O is bonded in a distorted L-shaped geometry to one K, one Cu, and one Te atom. In the second O site, O is bonded in a 4-coordinate geometry to two equivalent K, one Cu, and one Te atom. In the third O site, O is bonded in a distorted trigonal non-coplanar geometry to two equivalent K and one Te atom. In the fourth O site, O is bonded in a 4-coordinate geometry to four equivalent K atoms.
