The compound described by Sr2NBr is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Sr(1) is bonded to three equivalent N(1) and three equivalent Br(1) atoms to form a mixture of distorted edge and corner-sharing SrBr3N3 octahedra. The corner-sharing octahedra are not tilted. N(1) is bonded to six equivalent Sr(1) atoms to form NSr6 octahedra that share corners with six equivalent Br(1)Sr6 octahedra, edges with six equivalent N(1)Sr6 octahedra, and edges with six equivalent Br(1)Sr6 octahedra. The corner-sharing octahedral tilt angles are 15°. Br(1) is bonded to six equivalent Sr(1) atoms to form distorted BrSr6 octahedra that share corners with six equivalent N(1)Sr6 octahedra, edges with six equivalent N(1)Sr6 octahedra, and edges with six equivalent Br(1)Sr6 octahedra. The corner-sharing octahedral tilt angles are 15°. is represented by the CIF file [CIF]
