In the eighth Ta5+ site, Ta5+ is bonded to two equivalent N3- and four O2- atoms to form distorted TaN2O4 octahedra that share corners with four TaO6 octahedra and edges with four TaN2O4 octahedra. The corner-sharing octahedra tilt angles range from 6–37°. Both Ta–N bond lengths are 2.05 Å. There are a spread of Ta–O bond distances ranging from 1.86–2.30 Å. In the ninth Ta5+ site, Ta5+ is bonded in a 6-coordinate geometry to two equivalent N3- and four O2- atoms. Both Ta–N bond lengths are 2.07 Å. There are a spread of Ta–O bond distances ranging from 1.85–2.32 Å. There are three inequivalent N3- sites. In the first N3- site, N3- is bonded to four Ta5+ atoms to form distorted corner-sharing NTa4 tetrahedra. In the second N3- site, N3- is bonded in a 4-coordinate geometry to four Ta5+ atoms.
