Materials Data on Ba6Br2N3Cl by Materials Project
Ba6N3Br2Cl is Caswellsilverite-derived structured and crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded to three N3-, one Br1-, and two equivalent Cl1- atoms to form a mixture of distorted edge and corner-sharing BaBrN3Cl2 octahedra. The corner-sharing octahedral tilt angles are 0°. There are one shorter (2.84 Å) and two longer (2.85 Å) Ba–N bond lengths. The Ba–Br bond length is 3.44 Å. Both Ba–Cl bond lengths are 3.43 Å. In the second Ba2+ site, Ba2+ is bonded to three 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 2.83 Å. All Ba–Br bond lengths are 3.45 Å. In the third Ba2+ site, Ba2+ is bonded to three equivalent N3-, two equivalent Br1-, and one Cl1- atom to form a mixture of distorted edge and corner-sharing BaBr2N3Cl octahedra. The corner-sharing octahedral tilt angles are 0°. There are two shorter (2.83 Å) and one longer (2.85 Å) Ba–N bond lengths. Both Ba–Br bond lengths are 3.45 Å. The Ba–Cl bond length is 3.44 Å. There are two 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. Br1- is bonded in a 6-coordinate geometry to six Ba2+ atoms. Cl1- is bonded in a 6-coordinate geometry to six Ba2+ atoms.
