Materials Data on SbTe(ClF2)3 by Materials Project

Abstract

SbTe(ClF2)3 crystallizes in the orthorhombic Pnma space group. The structure is two-dimensional and consists of two SbTe(ClF2)3 sheets oriented in the (0, 0, 1) direction. Sb5+ is bonded in an octahedral geometry to six F1- atoms. There are a spread of Sb–F bond distances ranging from 1.90–1.95 Å. Te4+ is bonded in a 7-coordinate geometry to three Cl1- and four F1- atoms. All Te–Cl bond lengths are 2.31 Å. There are a spread of Te–F bond distances ranging from 2.67–3.00 Å. There are two 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. There are five inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted bent 150 degrees geometry to one Sb5+ and one Te4+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Sb5+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one Sb5+ and one Te4+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one Sb5+ atom. In the fifth F1- site, F1- is bonded in a distorted single-bond geometry to one Sb5+ and one Te4+ atom.
