Materials Data on Na3Ti8O16 by Materials Project
Na3Ti8O16 is beta indium sulfide-derived structured and crystallizes in the orthorhombic Pmmn space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to four O2- atoms to form NaO4 tetrahedra that share corners with twelve TiO6 octahedra. The corner-sharing octahedra tilt angles range from 60–63°. There are two shorter (2.14 Å) and two longer (2.16 Å) Na–O bond lengths. In the second Na1+ site, Na1+ is bonded to four O2- atoms to form NaO4 tetrahedra that share corners with twelve TiO6 octahedra. The corner-sharing octahedra tilt angles range from 59–62°. There are three shorter (2.15 Å) and one longer (2.17 Å) Na–O bond lengths. There are four inequivalent Ti+3.62+ sites. In the first Ti+3.62+ site, Ti+3.62+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with four NaO4 tetrahedra and edges with six TiO6 octahedra. There are a spread of Ti–O bond distances ranging from 2.01–2.03 Å. In the second Ti+3.62+ site, Ti+3.62+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with four NaO4 tetrahedra and edges with six TiO6 octahedra. There are a spread of Ti–O bond distances ranging from 2.00–2.05 Å. In the third Ti+3.62+ site, Ti+3.62+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with five NaO4 tetrahedra and edges with six TiO6 octahedra. There are a spread of Ti–O bond distances ranging from 1.96–2.08 Å. In the fourth Ti+3.62+ site, Ti+3.62+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with five NaO4 tetrahedra and edges with six TiO6 octahedra. There are a spread of Ti–O bond distances ranging from 1.99–2.05 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded to one Na1+ and three Ti+3.62+ atoms to form a mixture of distorted edge and corner-sharing ONaTi3 tetrahedra. In the second O2- site, O2- is bonded to one Na1+ and three Ti+3.62+ atoms to form a mixture of distorted edge and corner-sharing ONaTi3 tetrahedra. In the third O2- site, O2- is bonded to one Na1+ and three Ti+3.62+ atoms to form a mixture of distorted edge and corner-sharing ONaTi3 tetrahedra. In the fourth O2- site, O2- is bonded to one Na1+ and three Ti+3.62+ atoms to form a mixture of edge and corner-sharing ONaTi3 tetrahedra. In the fifth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to three Ti+3.62+ atoms. In the sixth O2- site, O2- is bonded to one Na1+ and three Ti+3.62+ atoms to form a mixture of distorted edge and corner-sharing ONaTi3 tetrahedra. In the seventh O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to three Ti+3.62+ atoms.
