Materials Data on LaSc3(BO3)4 by Materials Project

LaSc3(BO3)4 is Calcite-derived structured and crystallizes in the trigonal R32 space group. The structure is three-dimensional. La3+ is bonded to six equivalent O2- atoms to form distorted LaO6 pentagonal pyramids that share corners with six equivalent ScO6 pentagonal pyramids. All La–O bond lengths are 2.39 Å. Sc3+ is bonded to six O2- atoms to form distorted ScO6 pentagonal pyramids that share corners with two equivalent LaO6 pentagonal pyramids and corners with four equivalent ScO6 pentagonal pyramids. There are a spread of Sc–O bond distances ranging from 2.08–2.25 Å. There are two inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.38 Å) and one longer (1.39 Å) B–O bond length. In the second B3+ site, B3+ is bonded in a trigonal planar geometry to three equivalent O2- atoms. All B–O bond lengths are 1.39 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one La3+, one Sc3+, and one B3+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Sc3+ and one B3+ atom.
