Materials Data on Zr3N2O3 by Materials Project
Zr3N2O3 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are six inequivalent Zr4+ sites. In the first Zr4+ site, Zr4+ is bonded to two N3- and four O2- atoms to form distorted ZrN2O4 octahedra that share corners with four ZrN2O4 octahedra and edges with six ZrN3O3 octahedra. The corner-sharing octahedra tilt angles range from 27–42°. There are one shorter (2.10 Å) and one longer (2.23 Å) Zr–N bond lengths. There are a spread of Zr–O bond distances ranging from 2.09–2.29 Å. In the second Zr4+ site, Zr4+ is bonded to three N3- and three O2- atoms to form distorted ZrN3O3 octahedra that share corners with four ZrN3O3 octahedra and edges with six ZrN2O4 octahedra. The corner-sharing octahedra tilt angles range from 26–57°. There are a spread of Zr–N bond distances ranging from 2.13–2.22 Å. There are a spread of Zr–O bond distances ranging from 2.12–2.34 Å. In the third Zr4+ site, Zr4+ is bonded to three N3- and three O2- atoms to form distorted ZrN3O3 octahedra that share corners with four ZrN3O3 octahedra and edges with six ZrN2O4 octahedra. The corner-sharing octahedra tilt angles range from 21–57°. There are a spread of Zr–N bond distances ranging from 2.08–2.17 Å. There are a spread of Zr–O bond distances ranging from 2.07–2.42 Å. In the fourth Zr4+ site, Zr4+ is bonded to two N3- and four O2- atoms to form a mixture of distorted edge and corner-sharing ZrN2O4 octahedra. The corner-sharing octahedra tilt angles range from 21–36°. Both Zr–N bond lengths are 2.18 Å. There are a spread of Zr–O bond distances ranging from 2.13–2.17 Å. In the fifth Zr4+ site, Zr4+ is bonded to three N3- and three O2- atoms to form a mixture of distorted edge and corner-sharing ZrN3O3 octahedra. The corner-sharing octahedra tilt angles range from 27–57°. There are two shorter (2.14 Å) and one longer (2.21 Å) Zr–N bond lengths. There are a spread of Zr–O bond distances ranging from 2.13–2.45 Å. In the sixth Zr4+ site, Zr4+ is bonded to two N3- and four O2- atoms to form a mixture of distorted edge and corner-sharing ZrN2O4 octahedra. The corner-sharing octahedra tilt angles range from 28–57°. There are one shorter (2.07 Å) and one longer (2.26 Å) Zr–N bond lengths. There are a spread of Zr–O bond distances ranging from 2.12–2.30 Å. There are four inequivalent N3- sites. In the first N3- site, N3- is bonded to four Zr4+ atoms to form distorted NZr4 trigonal pyramids that share a cornercorner with one OZr4 trigonal pyramid, corners with two equivalent NZr4 trigonal pyramids, and edges with two equivalent NZr4 trigonal pyramids. In the second N3- site, N3- is bonded in a 3-coordinate geometry to three Zr4+ atoms. In the third N3- site, N3- is bonded to four Zr4+ atoms to form distorted NZr4 tetrahedra that share corners with two equivalent NZr4 tetrahedra, a cornercorner with one NZr4 trigonal pyramid, and edges with two equivalent OZr4 trigonal pyramids. In the fourth N3- site, N3- is bonded to four Zr4+ atoms to form a mixture of distorted edge and corner-sharing NZr4 trigonal pyramids. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded to four Zr4+ atoms to form distorted OZr4 trigonal pyramids that share a cornercorner with one NZr4 trigonal pyramid, corners with two equivalent OZr4 trigonal pyramids, and edges with two equivalent NZr4 tetrahedra. In the second O2- site, O2- is bonded in a 4-coordinate geometry to four Zr4+ atoms. In the third O2- site, O2- is bonded in a 3-coordinate geometry to three Zr4+ atoms. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to four Zr4+ atoms. In the fifth O2- site, O2- is bonded in a distorted T-shaped geometry to three Zr4+ atoms. In the sixth O2- site, O2- is bonded in a distorted T-shaped geometry to three Zr4+ atoms.
