Materials Data on La3B5O12 by Materials Project
La3B5O12 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of La–O bond distances ranging from 2.28–2.86 Å. In the second La3+ site, La3+ is bonded in a 1-coordinate geometry to nine O2- atoms. There are a spread of La–O bond distances ranging from 2.17–3.05 Å. There are four inequivalent B3+ sites. In the first B3+ site, B3+ is bonded to four O2- atoms to form corner-sharing BO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.40–1.54 Å. 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 1.35–1.41 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 1.37–1.40 Å. In the fourth B3+ site, B3+ is bonded to four O2- atoms to form corner-sharing BO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.46–1.52 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one La3+ and two B3+ atoms. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two La3+ and two B3+ atoms. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent B3+ atoms. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to two B3+ atoms. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to three La3+ and one B3+ atom. In the sixth O2- site, O2- is bonded in a trigonal planar geometry to three La3+ atoms. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent La3+ and one B3+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to three La3+ and one B3+ atom. In the ninth O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent La3+ and two B3+ atoms.
