In the first Zr4+ site, Zr4+ is bonded in a 7-coordinate geometry to one N3- and six O2- atoms. The Zr–N bond length is 2.11 Å. There are a spread of Zr–O bond distances ranging from 2.09–2.60 Å. In the second Zr4+ site, Zr4+ is bonded to three N3- and three O2- atoms to form a mixture of edge and corner-sharing ZrN3O3 octahedra. There are a spread of Zr–N bond distances ranging from 2.10–2.15 Å. There are two shorter (2.18 Å) and one longer (2.23 Å) Zr–O bond lengths. In the third Zr4+ site, Zr4+ is bonded in a 6-coordinate geometry to two N3- and four O2- atoms. There are one shorter (2.12 Å) and one longer (2.13 Å) Zr–N bond lengths. There are a spread of Zr–O bond distances ranging from 2.15–2.32 Å. In the fourth Zr4+ site, Zr4+ is bonded in a 7-coordinate geometry to two N3- and five O2- atoms.
