Materials Data on Sn4SF6 by Materials Project

Abstract

Sn4SF6 crystallizes in the trigonal R3 space group. The structure is three-dimensional. there are two inequivalent Sn2+ sites. In the first Sn2+ site, Sn2+ is bonded in a 2-coordinate geometry to one S2- and three F1- atoms. The Sn–S bond length is 2.68 Å. There are a spread of Sn–F bond distances ranging from 2.14–2.70 Å. In the second Sn2+ site, Sn2+ is bonded in a 6-coordinate geometry to six F1- atoms. There are three shorter (2.21 Å) and three longer (2.64 Å) Sn–F bond lengths. S2- is bonded in a distorted trigonal non-coplanar geometry to three equivalent Sn2+ atoms. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a 1-coordinate geometry to three Sn2+ atoms. In the second F1- site, F1- is bonded in a bent 150 degrees geometry to two Sn2+ atoms.
