Materials Data on TaBi4BrO8 by Materials Project
Abstract
TaBi4O8Br crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. Ta5+ is bonded to six O2- atoms to form corner-sharing TaO6 octahedra. The corner-sharing octahedra tilt angles range from 25–26°. There are a spread of Ta–O bond distances ranging from 1.91–2.14 Å. There are four inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Bi–O bond distances ranging from 2.26–2.88 Å. In the second Bi3+ site, Bi3+ is bonded in a 4-coordinate geometry to four O2- and four equivalent Br1- atoms. There are a spread of Bi–O bond distances ranging from 2.23–2.31 Å. There are a spread of Bi–Br bond distances ranging from 3.48–3.59 Å. In the third Bi3+ site, Bi3+ is bonded in a 4-coordinate geometry to four O2- and four equivalent Br1- atoms. There are a spread of Bi–O bond distances ranging from 2.23–2.32 Å. There are a spread of Bi–Br bond distances ranging from 3.47–3.60 Å. In the fourth Bi3+ site, Bi3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Bi–O bond distances ranging from 2.27–2.84 Å. There are eight inequivalent O2- sites.more »
