Materials Data on Sr2BrN by Materials Project
Sr2NBr is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Sr2+ is bonded to three equivalent N3- and three equivalent Br1- atoms to form a mixture of distorted edge and corner-sharing SrBr3N3 octahedra. The corner-sharing octahedral tilt angles are 0°. All Sr–N bond lengths are 2.65 Å. All Sr–Br bond lengths are 3.29 Å. N3- is bonded to six equivalent Sr2+ atoms to form edge-sharing NSr6 octahedra. Br1- is bonded in a 6-coordinate geometry to six equivalent Sr2+ atoms.
