Title: Materials Data on NdHoZr2O7 by Materials Project

Abstract

HoNdZr2O7 crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. Ho3+ is bonded in a distorted body-centered cubic geometry to eight O2- atoms. There are a spread of Ho–O bond distances ranging from 2.26–2.57 Å. Nd3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Nd–O bond distances ranging from 2.37–2.58 Å. There are two inequivalent Zr4+ sites. In the first Zr4+ site, Zr4+ is bonded to six O2- atoms to form corner-sharing ZrO6 octahedra. The corner-sharing octahedral tilt angles are 53°. All Zr–O bond lengths are 2.11 Å. In the second Zr4+ site, Zr4+ is bonded to six O2- atoms to form corner-sharing ZrO6 octahedra. The corner-sharing octahedral tilt angles are 53°. All Zr–O bond lengths are 2.11 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Ho3+ and two equivalent Nd3+ atoms to form ONd2Ho2 tetrahedra that share corners with sixteen ONd2Ho2 tetrahedra and edges with six ONd2Zr2 tetrahedra. In the second O2- site, O2- is bonded to two equivalent Nd3+ and two equivalent Zr4+ atoms to form a mixture of distorted corner and edge-sharing ONd2Zr2 tetrahedra. In the thirdmore » O2- site, O2- is bonded to two equivalent Ho3+ and two equivalent Zr4+ atoms to form a mixture of distorted corner and edge-sharing OHo2Zr2 tetrahedra. In the fourth O2- site, O2- is bonded to one Ho3+, one Nd3+, and two Zr4+ atoms to form a mixture of distorted corner and edge-sharing ONdHoZr2 tetrahedra.« less
