Materials Data on NaSrBO3 by Materials Project
NaSrBO3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Na1+ is bonded to six O2- atoms to form face-sharing NaO6 octahedra. There are a spread of Na–O bond distances ranging from 2.31–2.65 Å. Sr2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.61–2.86 Å. B3+ is bonded in a trigonal planar geometry to three 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 1-coordinate geometry to two equivalent Na1+, three equivalent Sr2+, and one B3+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Na1+, three equivalent Sr2+, and one B3+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Na1+, three equivalent Sr2+, and one B3+ atom.
