Materials Data on Sr3Sc(BO3)3 by Materials Project

Abstract

Sr3Sc(BO3)3 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Sr2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.52–2.95 Å. There are two inequivalent Sc3+ sites. In the first Sc3+ site, Sc3+ is bonded in an octahedral geometry to six equivalent O2- atoms. All Sc–O bond lengths are 2.16 Å. In the second Sc3+ site, Sc3+ is bonded in an octahedral geometry to six equivalent O2- atoms. All Sc–O bond lengths are 2.10 Å. 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 three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Sr2+, one Sc3+, and one B3+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to four equivalent Sr2+ and one B3+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to three equivalent Sr2+, one Sc3+, and one B3+ atom.
