Materials Data on Zr4N2O5 by Materials Project
Abstract
Zr4N2O5 crystallizes in the tetragonal I4cm space group. The structure is three-dimensional. there are seven inequivalent Zr4+ sites. In the first Zr4+ site, Zr4+ is bonded to two N3- and five O2- atoms to form distorted ZrN2O5 pentagonal bipyramids that share a cornercorner with one ZrN4O2 octahedra, corners with two ZrN2O5 pentagonal bipyramids, an edgeedge with one ZrN4O2 octahedra, and edges with six ZrN2O5 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 54°. There are one shorter (2.17 Å) and one longer (2.23 Å) Zr–N bond lengths. There are a spread of Zr–O bond distances ranging from 2.18–2.25 Å. In the second Zr4+ site, Zr4+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.20 Å) and four longer (2.30 Å) Zr–O bond lengths. In the third Zr4+ site, Zr4+ is bonded to four N3- and two equivalent O2- atoms to form a mixture of distorted edge and corner-sharing ZrN4O2 octahedra. There are two shorter (2.15 Å) and two longer (2.18 Å) Zr–N bond lengths. Both Zr–O bond lengths are 2.32 Å. In the fourth Zr4+ site, Zr4+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.20more »
