Materials Data on CuSnF6 by Materials Project

Abstract

CuSnF6 crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of one CuSnF6 ribbon oriented in the (1, 1, 1) direction. Cu2+ is bonded in a distorted square co-planar geometry to six F1- atoms. There are a spread of Cu–F bond distances ranging from 1.93–2.70 Å. Sn4+ is bonded in a linear geometry to two equivalent F1- atoms. Both Sn–F bond lengths are 1.18 Å. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Cu2+ atom. In the second F1- site, F1- is bonded in a 2-coordinate geometry to one Cu2+ and one Sn4+ atom. In the third F1- site, F1- is bonded in a 1-coordinate geometry to one Cu2+ atom.
