Zr5N5O2 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are ten inequivalent Zr+3.80+ sites. In the first Zr+3.80+ site, Zr+3.80+ is bonded in a 7-coordinate geometry to five N3- and two equivalent O2- atoms. There are a spread of Zr–N bond distances ranging from 2.31–2.48 Å. Both Zr–O bond lengths are 2.24 Å.

The corner-sharing octahedra tilt angles range from 4–62°. There are a spread of Zr–N bond distances ranging from 2.20–2.26 Å. The Zr–O bond length is 2.19 Å.
