Materials Data on Zr5N5O2 by Materials Project
Abstract
Zr5N5O2 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are five inequivalent Zr+3.80+ sites. In the first Zr+3.80+ site, Zr+3.80+ is bonded to five N3- and one O2- atom to form ZrN5O octahedra that share corners with three ZrN5O octahedra, corners with four equivalent ZrN5O2 pentagonal bipyramids, edges with five ZrN5O octahedra, and an edgeedge with one ZrN5O2 pentagonal bipyramid. The corner-sharing octahedra tilt angles range from 3–60°. There are two shorter (2.19 Å) and three longer (2.25 Å) Zr–N bond lengths. The Zr–O bond length is 2.22 Å. In the second 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 2.30–2.47 Å. Both Zr–O bond lengths are 2.24 Å. In the third Zr+3.80+ site, Zr+3.80+ is bonded to five N3- and two equivalent O2- atoms to form distorted ZrN5O2 pentagonal bipyramids that share corners with eight ZrN5O octahedra, edges with four ZrN5O octahedra, and faces with two equivalent ZrN5O2 pentagonal bipyramids. The corner-sharing octahedra tilt angles range from 21–69°. There are a spread of Zr–N bond distances ranging from 2.28–2.43 Å. There are one shorter (2.25 Å)more »
