Title: Materials Data on Ti3Nb2Cr3O16 by Materials Project

Abstract

Ti3Nb2Cr3O16 is beta Vanadium nitride-derived structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are three inequivalent Ti4+ sites. In the first Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with two equivalent NbO6 octahedra, an edgeedge with one NbO6 octahedra, and edges with four CrO6 octahedra. The corner-sharing octahedra tilt angles range from 51–53°. There are a spread of Ti–O bond distances ranging from 1.87–2.12 Å. In the second Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with two equivalent NbO6 octahedra, an edgeedge with one NbO6 octahedra, edges with two equivalent TiO6 octahedra, and edges with two equivalent CrO6 octahedra. The corner-sharing octahedral tilt angles are 51°. There are a spread of Ti–O bond distances ranging from 1.89–2.12 Å. In the third Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with two equivalent NbO6 octahedra, an edgeedge with one NbO6 octahedra, edges with two equivalent TiO6 octahedra, and edges with two equivalent CrO6 octahedra.
