Title: Materials Data on Nd4Zr3TiO14 by Materials Project

Abstract

Nd4Zr3TiO14 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are two inequivalent Nd3+ sites. In the first Nd3+ site, Nd3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are two shorter (2.33 Å) and six longer (2.59 Å) Nd–O bond lengths. In the second Nd3+ site, Nd3+ is bonded to eight O2- atoms to form distorted NdO8 hexagonal bipyramids that share edges with four equivalent NdO8 hexagonal bipyramids, edges with two equivalent TiO6 octahedra, and edges with four equivalent ZrO6 octahedra. There are a spread of Nd–O bond distances ranging from 2.31–2.65 Å. Zr4+ is bonded to six O2- atoms to form ZrO6 octahedra that share corners with two equivalent TiO6 octahedra, corners with four equivalent ZrO6 octahedra, and edges with four equivalent NdO8 hexagonal bipyramids. The corner-sharing octahedra tilt angles range from 47–53°. All Zr–O bond lengths are 2.12 Å. Ti4+ is bonded to six equivalent O2- atoms to form TiO6 octahedra that share corners with six equivalent ZrO6 octahedra and edges with six equivalent NdO8 hexagonal bipyramids. The corner-sharing octahedral tilt angles are 47°. All Ti–O bond lengths are 2.00 Å. There are three inequivalent O2- sites. In the firstmore » O2- site, O2- is bonded to four Nd3+ atoms to form ONd4 tetrahedra that share corners with ten ONd4 tetrahedra and edges with three equivalent ONd2Zr2 tetrahedra. In the second O2- site, O2- is bonded to two Nd3+ and two equivalent Zr4+ atoms to form a mixture of distorted edge and corner-sharing ONd2Zr2 tetrahedra. In the third O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Nd3+, one Zr4+, and one Ti4+ atom.« less
