Materials Data on TeAs(ClF2)3 by Materials Project
AsTe(ClF2)3 crystallizes in the monoclinic P2_1/c space group. The structure is one-dimensional and consists of two AsTe(ClF2)3 ribbons oriented in the (0, 0, 1) direction. As5+ is bonded in an octahedral geometry to six F1- atoms. There are a spread of As–F bond distances ranging from 1.75–1.82 Å. Te4+ is bonded in a 5-coordinate geometry to three Cl1- and two F1- atoms. There are a spread of Te–Cl bond distances ranging from 2.30–2.32 Å. There are one shorter (2.70 Å) and one longer (2.72 Å) Te–F bond lengths. There are three inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one Te4+ atom. In the second Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one Te4+ atom. In the third Cl1- site, Cl1- is bonded in a single-bond geometry to one Te4+ atom. There are six inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted single-bond geometry to one As5+ and one Te4+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one As5+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one As5+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one As5+ atom. In the fifth F1- site, F1- is bonded in a single-bond geometry to one As5+ atom. In the sixth F1- site, F1- is bonded in a distorted single-bond geometry to one As5+ and one Te4+ atom.
