Title: Materials Data on Bi4B2O9 by Materials Project

Abstract

Bi4B2O9 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.38–1.40 Å. In the second B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.38 Å) and one longer (1.40 Å) B–O bond length. There are four inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Bi–O bond distances ranging from 2.27–3.02 Å. In the second 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 2.25–2.89 Å. In the third Bi3+ site, Bi3+ is bonded to seven O2- atoms to form a mixture of distorted edge and corner-sharing BiO7 pentagonal bipyramids. The corner-sharing octahedra tilt angles range from 40–56°. There are a spread of Bi–O bond distances ranging from 2.32–2.69 Å. In the fourth Bi3+ site, Bi3+ is bonded to six O2- atoms to form distorted BiO6more » octahedra that share corners with two equivalent BiO6 octahedra, corners with four equivalent BiO7 pentagonal bipyramids, an edgeedge with one BiO6 octahedra, and an edgeedge with one BiO7 pentagonal bipyramid. The corner-sharing octahedral tilt angles are 78°. There are a spread of Bi–O bond distances ranging from 2.19–2.65 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to four Bi3+ atoms. In the second O2- site, O2- is bonded to four Bi3+ atoms to form edge-sharing OBi4 tetrahedra. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one B3+ and three Bi3+ atoms. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to three Bi3+ atoms. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one B3+ and three Bi3+ atoms. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to one B3+ and three Bi3+ atoms. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to one B3+ and three Bi3+ atoms. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to one B3+ and two Bi3+ atoms. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to one B3+ and three Bi3+ atoms.« less
