The material structure described by Sr2NCl is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Sr(1) is bonded to three equivalent N(1) and three equivalent Cl(1) atoms to form a mixture of distorted edge and corner-sharing SrN3Cl3 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 Cl(1)Sr6 octahedra, edges with six equivalent N(1)Sr6 octahedra, and edges with six equivalent Cl(1)Sr6 octahedra. The corner-sharing octahedral tilt angles are 13°. Cl(1) is bonded to six equivalent Sr(1) atoms to form distorted ClSr6 octahedra that share corners with six equivalent N(1)Sr6 octahedra, edges with six equivalent N(1)Sr6 octahedra, and edges with six equivalent Cl(1)Sr6 octahedra. The corner-sharing octahedral tilt angles are 13°. is represented by the CIF file [CIF]
