Abstract

NaTi3AlO8 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. Na1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are two shorter (2.44 Å) and two longer (2.49 Å) Na–O bond lengths. There are three inequivalent Ti4+ sites. In the first Ti4+ site, Ti4+ is bonded to six O2- atoms to form distorted TiO6 octahedra that share a cornercorner with one AlO6 octahedra, corners with three TiO6 octahedra, an edgeedge with one AlO6 octahedra, and edges with three TiO6 octahedra. The corner-sharing octahedra tilt angles range from 17–28°. There are a spread of Ti–O bond distances ranging from 1.80–2.26 Å. In the second Ti4+ site, Ti4+ is bonded to six O2- atoms to form distorted TiO6 octahedra that share a cornercorner with one AlO6 octahedra, corners with three TiO6 octahedra, edges with two TiO6 octahedra, and edges with two equivalent AlO6 octahedra. The corner-sharing octahedra tilt angles range from 19–28°. There are a spread of Ti–O bond distances ranging from 1.85–2.17 Å. In the third Ti4+ site, Ti4+ is bonded to six O2- atoms to form distorted TiO6 octahedra that share corners with four TiO6 octahedra, edges with two equivalent AlO6 octahedra, and edges withmore »« less
