Materials Data on TiNb2Zn(PbO3)4 by Materials Project
Abstract
TiNb2Zn(PbO3)4 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with two NbO6 octahedra, corners with four equivalent TiO6 octahedra, and faces with four equivalent PbO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 3–6°. There are a spread of Ti–O bond distances ranging from 1.91–2.15 Å. There are two inequivalent Nb5+ sites. In the first Nb5+ site, Nb5+ is bonded to six O2- atoms to form NbO6 octahedra that share a cornercorner with one TiO6 octahedra, a cornercorner with one ZnO6 octahedra, and corners with four equivalent NbO6 octahedra. The corner-sharing octahedra tilt angles range from 5–10°. There are a spread of Nb–O bond distances ranging from 1.91–2.16 Å. In the second Nb5+ site, Nb5+ is bonded to six O2- atoms to form NbO6 octahedra that share a cornercorner with one TiO6 octahedra, a cornercorner with one ZnO6 octahedra, corners with four equivalent NbO6 octahedra, and faces with four equivalent PbO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 3–14°. There are a spread of Nb–O bond distances ranging from 1.87–2.21 Å. Zn2+ is bonded to six O2- atoms to form ZnO6 octahedramore »
