Materials Data on Ba2BrN by Materials Project
Ba2NBr is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Ba2+ is bonded to three equivalent N3- and three equivalent Br1- atoms to form a mixture of distorted edge and corner-sharing BaBr3N3 octahedra. The corner-sharing octahedral tilt angles are 0°. All Ba–N bond lengths are 2.84 Å. All Ba–Br bond lengths are 3.49 Å. N3- is bonded to six equivalent Ba2+ atoms to form edge-sharing NBa6 octahedra. Br1- is bonded in a 6-coordinate geometry to six equivalent Ba2+ atoms.
