Abstract

TiTa2O6 is beta Vanadium nitride-derived structured and crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two 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 TiO6 octahedra, corners with six equivalent TaO6 octahedra, and edges with two equivalent TaO6 octahedra. The corner-sharing octahedra tilt angles range from 49–50°. There are a spread of Ti–O bond distances ranging from 2.08–2.10 Å. In the second Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with two equivalent TiO6 octahedra, corners with six equivalent TaO6 octahedra, and edges with two equivalent TaO6 octahedra. The corner-sharing octahedra tilt angles range from 45–49°. There are two shorter (2.03 Å) and four longer (2.10 Å) Ti–O bond lengths. There are two inequivalent Ta4+ sites. In the first Ta4+ site, Ta4+ is bonded to six O2- atoms to form TaO6 octahedra that share corners with three equivalent TiO6 octahedra, corners with five equivalent TaO6 octahedra, an edgeedge with one TiO6 octahedra, and an edgeedge with one TaO6 octahedra.
