Materials Data on TeC6(ClF7)2 by Materials Project

Abstract

(CF2)2(CF3)2C2Te(ClF2)2 crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of eight difluoromethane molecules, eight fluoroform molecules, and four C2Te(ClF2)2 clusters. In each C2Te(ClF2)2 cluster, C3+ is bonded in a water-like geometry to one Te2- and two F1- atoms. The C–Te bond length is 2.34 Å. Both C–F bond lengths are 1.35 Å. Te2- is bonded in a distorted rectangular see-saw-like geometry to two equivalent C3+ and two equivalent Cl1- atoms. Both Te–Cl bond lengths are 2.49 Å. Cl1- is bonded in a distorted single-bond geometry to one Te2- atom. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one C3+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one C3+ atom.
