Title: Materials Data on Zr2N2O by Materials Project

Abstract

Zr2ON2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent Zr4+ sites. In the first Zr4+ site, Zr4+ is bonded to four N3- and two equivalent O2- atoms to form a mixture of corner and edge-sharing ZrN4O2 octahedra. The corner-sharing octahedral tilt angles are 0°. There are a spread of Zr–N bond distances ranging from 2.09–2.17 Å. Both Zr–O bond lengths are 2.39 Å. In the second Zr4+ site, Zr4+ is bonded in a 7-coordinate geometry to four N3- and three equivalent O2- atoms. There are a spread of Zr–N bond distances ranging from 2.18–2.32 Å. There are two shorter (2.22 Å) and one longer (2.50 Å) Zr–O bond lengths. In the third Zr4+ site, Zr4+ is bonded in a 7-coordinate geometry to five N3- and two O2- atoms. There are a spread of Zr–N bond distances ranging from 2.13–2.41 Å. There are one shorter (2.24 Å) and one longer (2.73 Å) Zr–O bond lengths. There are three inequivalent N3- sites. In the first N3- site, N3- is bonded to four Zr4+ atoms to form distorted NZr4 tetrahedra that share corners with two equivalent OZr6 octahedra, corners with four NZr4 tetrahedra, an edgeedge withmore » one OZr6 octahedra, and an edgeedge with one NZr4 tetrahedra. The corner-sharing octahedral tilt angles are 12°. In the second N3- site, N3- is bonded to four Zr4+ atoms to form NZr4 tetrahedra that share a cornercorner with one OZr6 octahedra, corners with four NZr4 tetrahedra, edges with two equivalent OZr6 octahedra, and edges with two equivalent NZr4 tetrahedra. The corner-sharing octahedral tilt angles are 45°. In the third N3- site, N3- is bonded in a 5-coordinate geometry to five Zr4+ atoms. There are two 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 to six Zr4+ atoms to form distorted OZr6 octahedra that share corners with six NZr4 tetrahedra, edges with two equivalent OZr6 octahedra, and edges with six NZr4 tetrahedra.« less
