Materials Data on Ca3La3(BO3)5 by Materials Project
Ca3La3(BO3)5 crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. Ca2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.33–2.69 Å. La3+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of La–O bond distances ranging from 2.50–2.84 Å. There are three inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a trigonal planar geometry to three equivalent O2- atoms. All B–O bond lengths are 1.38 Å. In the second B3+ site, B3+ is bonded in a trigonal planar geometry to three equivalent O2- atoms. All B–O bond lengths are 1.40 Å. In the third B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.37 Å) and two longer (1.40 Å) B–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Ca2+, two equivalent La3+, and one B3+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent La3+ and one B3+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ca2+, two equivalent La3+, and one B3+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Ca2+, one La3+, and one B3+ atom.
