Materials Data on TeCF2 by Materials Project

Abstract

CTeF2 crystallizes in the monoclinic P2_1 space group. The structure is zero-dimensional and consists of four 1,3-ditelluretane, 2,2,4,4-tetrafluoro- molecules. there are two inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a distorted water-like geometry to two Te2- and two F1- atoms. There are one shorter (2.23 Å) and one longer (2.24 Å) C–Te bond lengths. There is one shorter (1.37 Å) and one longer (1.38 Å) C–F bond length. In the second C4+ site, C4+ is bonded in a distorted water-like geometry to two Te2- and two F1- atoms. There are one shorter (2.23 Å) and one longer (2.24 Å) C–Te bond lengths. There is one shorter (1.37 Å) and one longer (1.38 Å) C–F bond length. There are two inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 2-coordinate geometry to two C4+ atoms. In the second Te2- site, Te2- is bonded in a 2-coordinate geometry to two C4+ atoms. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one C4+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one C4+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one C4+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one C4+ atom.
