Materials Data on TeF6 by Materials Project

TeF6 is beta Np structured and crystallizes in the orthorhombic Pnma space group. The structure is zero-dimensional and consists of four TeF6 clusters. Te6+ is bonded in an octahedral geometry to six F1- atoms. There is two shorter (1.86 Å) and four longer (1.87 Å) Te–F bond length. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Te6+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Te6+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one Te6+ atom.

Materials Data on TeF4 by Materials Project

TeF4 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is one-dimensional and consists of two TeF4 ribbons oriented in the (0, 1, 0) direction. Te4+ is bonded to five F1- atoms to form distorted corner-sharing TeF5 square pyramids. There are a spread of Te–F bond distances ranging from 1.88–2.25 Å. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Te4+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Te4+ atom. In the third F1- site, F1- is bonded in a bent 150 degrees geometry to two equivalent Te4+ atoms. In the fourth F1- site, F1- is bonded in a single-bond geometry to one Te4+ atom.
