Materials Data on NaSr4(BN2)3 by Materials Project
NaSr4(BN2)3 crystallizes in the cubic Im-3m space group. The structure is three-dimensional. Na1+ is bonded to six equivalent N3- atoms to form NaN6 octahedra that share faces with eight equivalent SrN6 octahedra. All Na–N bond lengths are 2.45 Å. Sr2+ is bonded to six equivalent N3- atoms to form distorted SrN6 octahedra that share corners with six equivalent SrN6 octahedra, edges with six equivalent SrN6 octahedra, and faces with two equivalent NaN6 octahedra. The corner-sharing octahedral tilt angles are 23°. All Sr–N bond lengths are 2.74 Å. B3+ is bonded in a linear geometry to two equivalent N3- atoms. Both B–N bond lengths are 1.35 Å. N3- is bonded in a 1-coordinate geometry to one Na1+, four equivalent Sr2+, and one B3+ atom.
