Materials Data on KTeF5 by Materials Project

Abstract

KTeF5 crystallizes in the orthorhombic Pbcm space group. The structure is three-dimensional. K1+ is bonded in a 10-coordinate geometry to ten F1- atoms. There are a spread of K–F bond distances ranging from 2.74–3.07 Å. Te4+ is bonded in a square pyramidal geometry to five F1- atoms. There are a spread of Te–F bond distances ranging from 1.92–2.01 Å. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted single-bond geometry to two equivalent K1+ and one Te4+ atom. In the second F1- site, F1- is bonded in a 2-coordinate geometry to two equivalent K1+ and one Te4+ atom. In the third F1- site, F1- is bonded in a 1-coordinate geometry to two equivalent K1+ and one Te4+ atom.
