Title: Materials Data on Zr2N2O by Materials Project

Abstract

Zr2ON2 crystallizes in the monoclinic Pm 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 three O2- atoms to form distorted ZrN4O3 pentagonal bipyramids that share corners with two equivalent ZrN6O pentagonal bipyramids and edges with four ZrN4O3 pentagonal bipyramids. There are a spread of Zr–N bond distances ranging from 2.16–2.27 Å. There are one shorter (2.28 Å) and two longer (2.32 Å) Zr–O bond lengths. In the second Zr4+ site, Zr4+ is bonded in a 8-coordinate geometry to three N3- and five O2- atoms. There are one shorter (2.26 Å) and two longer (2.29 Å) Zr–N bond lengths. There are a spread of Zr–O bond distances ranging from 2.25–2.65 Å. In the third Zr4+ site, Zr4+ 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 2.23–2.35 Å. Both Zr–O bond lengths are 2.34 Å. In the fourth Zr4+ site, Zr4+ is bonded to five N3- and two O2- atoms to form a mixture of distorted edge and corner-sharing ZrN5O2 pentagonal bipyramids. There are a spread of Zr–N bond distancesmore » ranging from 2.19–2.28 Å. There are one shorter (2.28 Å) and one longer (2.33 Å) Zr–O bond lengths.

In the fourth N3- site, N3- is bonded to five Zr4+ atoms to form a mixture of distorted edge and corner-sharing NZr5 trigonal bipyramids. In the fifth N3- site, N3- is bonded to five Zr4+ atoms to form distorted NZr5 square pyramids that share corners with two equivalent NZr5 square pyramids, corners with two equivalent OZr5 square pyramids, corners with four NZr5 trigonal bipyramids, edges with three NZr5 square pyramids, and an edgeedge with one NZr5 trigonal bipyramid. In the sixth N3- site, N3- is bonded in a 4-coordinate geometry to five Zr4+ atoms. In the seventh N3- site, N3- is bonded in a 5-coordinate geometry to five Zr4+ atoms.
