Materials Data on Ba10IBr4N5 by Materials Project
Ba10N5IBr4 is Caswellsilverite-derived structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are five inequivalent Ba2+ sites. In the first Ba2+ site, 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 2.85 Å. All Ba–Br bond lengths are 3.50 Å. In the second Ba2+ site, Ba2+ is bonded to three equivalent N3- and three equivalent I1- atoms to form a mixture of distorted edge and corner-sharing BaI3N3 octahedra. The corner-sharing octahedral tilt angles are 0°. All Ba–N bond lengths are 2.83 Å. All Ba–I bond lengths are 3.62 Å. In the third Ba2+ site, 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. In the fourth Ba2+ site, 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 2.85 Å. All Ba–Br bond lengths are 3.52 Å. In the fifth Ba2+ site, 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 2.85 Å. All Ba–Br bond lengths are 3.52 Å. There are three inequivalent N3- sites. In the first N3- site, N3- is bonded to six Ba2+ atoms to form edge-sharing NBa6 octahedra. In the second N3- site, N3- is bonded to six Ba2+ atoms to form edge-sharing NBa6 octahedra. In the third N3- site, N3- is bonded to six equivalent Ba2+ atoms to form edge-sharing NBa6 octahedra. I1- is bonded in a 6-coordinate geometry to six equivalent Ba2+ atoms. There are two inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a 6-coordinate geometry to six Ba2+ atoms. In the second Br1- site, Br1- is bonded in a 6-coordinate geometry to six Ba2+ atoms.
