Materials Data on Bi2OF4 by Materials Project

Abstract

Bi2OF4 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Bi3+ is bonded in a 8-coordinate geometry to two equivalent O2- and six F1- atoms. There are one shorter (2.34 Å) and one longer (2.35 Å) Bi–O bond lengths. There are a spread of Bi–F bond distances ranging from 2.38–2.61 Å. O2- is bonded to four equivalent Bi3+ atoms to form distorted edge-sharing OBi4 tetrahedra. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a 3-coordinate geometry to three equivalent Bi3+ atoms. In the second F1- site, F1- is bonded in a 3-coordinate geometry to three equivalent Bi3+ atoms.
