Materials Data on Bi3O4F by Materials Project

Abstract

Bi3O4F crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded in a rectangular see-saw-like geometry to three O2- and one F1- atom. There are a spread of Bi–O bond distances ranging from 2.12–2.21 Å. The Bi–F bond length is 2.50 Å. In the second Bi3+ site, Bi3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Bi–O bond distances ranging from 2.27–2.63 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to three Bi3+ atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to three Bi3+ atoms. F1- is bonded in a linear geometry to two equivalent Bi3+ atoms.
