Title: Materials Data on Zr2N2O by Materials Project

Abstract

Zr2ON2 is Ilmenite-like structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are eight inequivalent Zr4+ sites. In the first Zr4+ site, Zr4+ is bonded to four N3- and two O2- atoms to form a mixture of distorted edge, face, and corner-sharing ZrN4O2 octahedra. The corner-sharing octahedra tilt angles range from 44–65°. There are a spread of Zr–N bond distances ranging from 2.09–2.30 Å. There are one shorter (2.19 Å) and one longer (2.44 Å) Zr–O bond lengths. In the second Zr4+ site, Zr4+ is bonded to four N3- and two O2- atoms to form a mixture of distorted edge, face, and corner-sharing ZrN4O2 octahedra. The corner-sharing octahedra tilt angles range from 42–67°. There are a spread of Zr–N bond distances ranging from 2.11–2.39 Å. There are one shorter (2.11 Å) and one longer (2.32 Å) Zr–O bond lengths. In the third Zr4+ site, Zr4+ is bonded to four N3- and two O2- atoms to form a mixture of distorted edge, face, and corner-sharing ZrN4O2 octahedra. The corner-sharing octahedra tilt angles range from 46–67°. There are a spread of Zr–N bond distances ranging from 2.12–2.34 Å. There are one shorter (2.17 Å) and one longermore » (2.36 Å) Zr–O bond lengths. In the fourth Zr4+ site, Zr4+ is bonded to four N3- and two O2- atoms to form a mixture of distorted edge, face, and corner-sharing ZrN4O2 octahedra.

There are one shorter (2.20 Å) and one longer (2.42 Å) Zr–O bond lengths. In the eighth Zr4+ site, Zr4+ is bonded to four N3- and two O2- atoms to form a mixture of distorted edge, face, and corner-sharing ZrN4O2 octahedra. The corner-sharing octahedra tilt angles range from 47–66°. There are a spread of Zr–N bond distances ranging from 2.11–2.35 Å. There are one shorter (2.16 Å) and one longer (2.35 Å) Zr–O bond lengths. There are eight inequivalent N3- sites. In the first N3- site, N3- is bonded to four Zr4+ atoms to form a mixture of distorted edge and corner-sharing NZr4 trigonal pyramids. In the second N3- site, N3- is bonded to four Zr4+ atoms to form a mixture of distorted edge and corner-sharing NZr4 trigonal pyramids. In the third N3- site, N3- is bonded to four Zr4+ atoms to form a mixture of distorted edge and corner-sharing NZr4 trigonal pyramids. In the fourth N3- site, N3- is bonded in a distorted see-saw-like geometry to four Zr4+ atoms. In the fifth N3- site, N3- is bonded to four Zr4+ atoms to form distorted corner-sharing NZr4 trigonal pyramids. In the sixth N3- site, N3- is bonded to four Zr4+ atoms to form a mixture of distorted edge and corner-sharing NZr4 trigonal pyramids.

There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to four Zr4+ atoms. 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 4-coordinate geometry to four Zr4+ atoms. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to four Zr4+ atoms.« less
