Materials Data on Sr3Y(BO3)3 by Materials Project
Sr3Y(BO3)3 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.49–3.04 Å. There are two inequivalent Y3+ sites. In the first Y3+ site, Y3+ is bonded in an octahedral geometry to six equivalent O2- atoms. All Y–O bond lengths are 2.25 Å. In the second Y3+ site, Y3+ is bonded in an octahedral geometry to six equivalent O2- atoms. All Y–O bond lengths are 2.32 Å. B3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.38–1.40 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Sr2+ and one B3+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to three equivalent Sr2+, one Y3+, and one B3+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Sr2+, one Y3+, and one B3+ atom.
