Materials Data on Ho4Zr3O12 by Materials Project
Abstract
Ho4Zr3O12 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are four inequivalent Ho3+ sites. In the first Ho3+ site, Ho3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ho–O bond distances ranging from 2.20–2.69 Å. In the second Ho3+ site, Ho3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ho–O bond distances ranging from 2.24–2.61 Å. In the third Ho3+ site, Ho3+ is bonded to seven O2- atoms to form distorted HoO7 pentagonal bipyramids that share a cornercorner with one ZrO6 octahedra and an edgeedge with one ZrO6 octahedra. The corner-sharing octahedral tilt angles are 52°. There are a spread of Ho–O bond distances ranging from 2.19–2.51 Å. In the fourth Ho3+ site, Ho3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ho–O bond distances ranging from 2.22–2.62 Å. There are three inequivalent Zr4+ sites. In the first Zr4+ site, Zr4+ is bonded to six O2- atoms to form ZrO6 octahedra that share a cornercorner with one HoO7 pentagonal bipyramid and an edgeedge with one HoO7 pentagonal bipyramid. There are a spread of Zr–O bondmore »
