The structure described by NaSr4(BN2)3 crystallizes in the cubic Im-3m space group. Na(1) is bonded to six equivalent N(1) atoms to form NaN6 octahedra that share faces with eight equivalent Sr(1)N6 octahedra. Sr(1) is bonded to six equivalent N(1) atoms to form distorted SrN6 octahedra that share corners with six equivalent Sr(1)N6 octahedra, edges with six equivalent Sr(1)N6 octahedra, and faces with two equivalent Na(1)N6 octahedra. The corner-sharing octahedral tilt angles are 23°. B(1) is bonded in a linear geometry to two equivalent N(1) atoms. N(1) is bonded in a 6-coordinate geometry to one Na(1), four equivalent Sr(1), and one B(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
