Materials Data on Bi(BO2)3 by Materials Project

BiB3O6 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are three inequivalent B3+ sites. In the first B3+ site, B3+ is bonded to four O2- atoms to form BO4 tetrahedra that share corners with two equivalent BiO6 pentagonal pyramids. There is two shorter (1.45 Å) and two longer (1.51 Å) B–O bond length. In the second 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 1.34–1.41 Å. In the third 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 1.35–1.41 Å. Bi3+ is bonded to six O2- atoms to form distorted BiO6 pentagonal pyramids that share corners with four equivalent BiO6 pentagonal pyramids and corners with two equivalent BO4 tetrahedra. There are a spread of Bi–O bond distances ranging from 2.17–2.62 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two B3+ atoms. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two B3+ atoms. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two B3+ and one Bi3+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two B3+ and one Bi3+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to one B3+ and two equivalent Bi3+ atoms. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to one B3+ and two equivalent Bi3+ atoms.
