Title: Materials Data on Bi4O3F7 by Materials Project

Abstract

Bi4O3F7 crystallizes in the monoclinic Pm space group. The structure is three-dimensional. there are four inequivalent Bi+3.25+ sites. In the first Bi+3.25+ site, Bi+3.25+ is bonded in a 8-coordinate geometry to three O2- and five F1- atoms. There are one shorter (2.28 Å) and two longer (2.46 Å) Bi–O bond lengths. There are a spread of Bi–F bond distances ranging from 2.38–2.73 Å. In the second Bi+3.25+ site, Bi+3.25+ is bonded in a 7-coordinate geometry to three O2- and four F1- atoms. There are one shorter (2.31 Å) and two longer (2.47 Å) Bi–O bond lengths. There are a spread of Bi–F bond distances ranging from 2.43–2.46 Å. In the third Bi+3.25+ site, Bi+3.25+ is bonded in a 9-coordinate geometry to two O2- and seven F1- atoms. There are one shorter (2.53 Å) and one longer (2.57 Å) Bi–O bond lengths. There are a spread of Bi–F bond distances ranging from 2.24–2.59 Å. In the fourth Bi+3.25+ site, Bi+3.25+ is bonded in a distorted body-centered cubic geometry to four O2- and four F1- atoms. There are two shorter (2.27 Å) and two longer (2.44 Å) Bi–O bond lengths. There are two shorter (2.36 Å) and two longer (2.53 Å) Bi–Fmore » bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to four Bi+3.25+ atoms to form distorted OBi4 tetrahedra that share corners with two equivalent OBi4 tetrahedra and corners with two equivalent FBi4 tetrahedra. In the second O2- site, O2- is bonded in a 4-coordinate geometry to four Bi+3.25+ atoms. In the third O2- site, O2- is bonded in a 4-coordinate geometry to four Bi+3.25+ atoms. There are seven inequivalent F1- sites. In the first F1- site, F1- is bonded to four Bi+3.25+ atoms to form distorted FBi4 tetrahedra that share corners with two equivalent OBi4 tetrahedra and corners with two equivalent FBi4 tetrahedra. In the second F1- site, F1- is bonded in a distorted trigonal non-coplanar geometry to three Bi+3.25+ atoms. In the third F1- site, F1- is bonded in a distorted trigonal non-coplanar geometry to three Bi+3.25+ atoms. In the fourth F1- site, F1- is bonded in a 2-coordinate geometry to three Bi+3.25+ atoms. In the fifth F1- site, F1- is bonded in a 3-coordinate geometry to three Bi+3.25+ atoms. In the sixth F1- site, F1- is bonded in a distorted single-bond geometry to one Bi+3.25+ atom. In the seventh F1- site, F1- is bonded in a 3-coordinate geometry to three Bi+3.25+ atoms.« less
